Hi, I have a problem with errors=panic on ext3. When a panic occurs, the error event is not recorded anywhere. So after the reboot, e2fsck doesn't kick in, the file system gets mounted again and the box panics again... Patch below moves the ERRORS_PANIC test down a bit so the journal is aborted before panic() is called. Eric Signed-off-by: Eric Lammerts <eric at lammerts.org> ---

Hello all. I just upgraded to the latest and tried to reboot: kernel panic and dead as a brick. Luckily GRUB still works and booting the to the next option in boot menu succeeds. How can this be? This OS is assumed to be solid as a brick :) br. jarif -------------- next part -------------- A non-text attachment was scrubbed... Name: signature.asc Type: application/pgp-signature Size: 195

...panics (all vm_page_unwire) on one of those systems only (amd64 server) during the past week. The first two panics were triggered when shutting down the ntpd daemon (a recent development snapshot version of ntpd: 4.2.7p387). Exiting a later release (p388) has not triggered the panic. The system panicked again overnight, this time while acting as an sftp server receiving large (GB) files from another system.

This OS is assumed to be solid as a brick :) It's hard to diagnose if the only thing you say is that it panicked. If it's panicking because it can't find the root disk, then that's a completely different issue than it panicking when it loads a particular driver. -- Jonathan Billings <billings at negate.org>

...kernel. since it was getting close to end of day, i wanted to keep it simple and directed them to just "make defconfig" to see what would happen. the configuration and build of the kernel and modules worked fine, they installed the kernel and modules, then rebooted but the new kernel panicked almost immediately, apparently whining that it couldn't mount the root filesystem. since they were all running LVM-based systems, i assumed that perhaps we needed to explicitly add LVM support during the config step. i'd still like to be able to build and boot a new kernel on an updat...

...ers, booting them off the SystemRescueCD, mounting all the partition on /mnt/transfer etc Ran rsync to copy all the data from one to the other - except /boot and /lib/modules Brought the blade up, and saw that it booted fine. However, a new kernel has been released and we tried rebooting... And it panicked. It seems to be LVM related, in that it can't mount /dev/root - and I've tried manually running mkinitrd to regenerate the initrd to no avail. I was just wondering if anyone had encountered similar problems, and knew of any solutions? I'm from a debian background, so am a little unu...

It'd probably help if you could give us more details on the kernel panic. Can you see where it is panicking? Does it happen during the kernel/initrd stage or later during boot? I suggest installing the kdump service if it is panicking later in boot, you might be able to capture a kernel dump which makes debugging these things a lot easier. Otherwise, I suggest trying to capture the panic message so...

I've restarted Dovecot, and, I think it's OK now sorry, I've panicked as googling turned multiple iphone/certs issue, and, rather than properly testing first, I stupidly panicked... thanks for explanation, thanks for testing!! so, basically, after each renewal of server's cert I should remember to reload Dovecot (and maybe Postfix too?) thanks again, -- Vo...

Interesting article on multi-booting the developer Intel based Mac with MacOS, WinXP and you guessed it: CentOS! Way to go, especially since Fedora kernel panicked on them.... http://www.jasbone.com/blog/archives/2005/07/multibooting_in.html cya, TR -- Todd Rittinger TLC Solutions www.tlcsolutions.ca

Hi Which is the best interface card to connect PSTN line with Asterisk. Can somebody please help. My intention is to route the incoming PSTN calls to internal IP Phones through Asterisk and Vice versa. The Asterisk is in LAN and is reachable from all the IP phones in the LAN.

I'm running CentOS 5.2, it uses LVM to manage the disks and we had a programmer do something (not sure what) then reboot the system. When it came up it kernel panicked. Luckily it's not production, it was their sandbox. But they didn't backup any of their files. I know the disks are fine because I was able to boot from a linux live cd and mount the /boot partition from the sda drive, and the sdb drive that has the mysql database mounted at /var/lib/m...

Hello, trying out btrfs on my linux installation. I am running Funtoo with Linux 3.0 kernel. After a reboot kernel panicked (no access to error log since it is my root volume that failed). I get this using a rescue cd (2.6.38, btrfs v 0.19) and then trying to mount : [  752.129118] btrfs bad tree block start 0 131072 [  752.129152] btrfs: failed to read chunk root on sda5 [  752.132190] btrfs: open_ctree failed [ 113...

Hi All After upgrading to 7.2, I'm getting an immediate kernel panic on boot Dropping back to 3.10.0-229.20.1.el7.x86_64 and the system boots fine How can I go about diagnosing the problem here? thanks Duncan

...l (sorry if I misinterpreted your point). I disagree: embedded system of RAID card and RAID function they have to fulfill are much simpler than everything involved into software RAID. Therefore, with the same effort invested, firmware of (good) hardware is less buggy. And again, Linux kernel can be panicked more likely than trivial embedded system of hardware RAID card/box. At least my experience over decade and a half confirms that. I have heard horror stories from people who used the same good hardware I mentioned (3ware). However, when I went in each case deep into detail I discovered that they...

Thanks for the response, Eli. The header suggestion could certainly cause this issue (I panicked for a second), but unfortunately as far as I can tell the headers are in fact from LLVM 2.7. The pass is built as a project configured by llvm, so hopefully that would make things right, but also: --include paths look legit (make VERBOSE=1, etc) --strace on the build process for the project conf...

...ssword then hang forever without printing anything. SSH login will block forever without prompting for user or password. Machine responds to ping. NFS drops. snv_113, this has occurred since the RAID-Z2 was created (b102). I have no idea how to instrument this, as it doesn''t appear to be panicking, or running out of RAM (as far as I can see from the last responses of top and prstat), and I don''t know how to ask dtrace about where I''m mostly spending my time.
