I've finally been able to capture the panic, as now it occurs even with DDB configured.

I just recently posted a patch to the linux-kernel mailing list to move rootfs/initramfs from ramfs to tmpfs. Now I'd like to test this out better. Currently I'm only using initramfs to store data so I'm new the this klibc thing. Tommorrow I'm going to try to get klibc working to run some programs in early-userspace. From what I've read so far, i'll need a swapon

Hello All! My 1st use of CentOS went well on my later eqpt. Thanks and congrats on a good product. Figured I might as well see if I could use it on some old stuff, still good but obsolete. Picked an AMD 5x86 (equivalent to a Pentium 75 MHz) and decided to see if I could make it my gateway/router. Had some difficulties, not unexpected. Old CD drive couldn't read the CDs. No boot from CD

.... I have a CentOS 5.n VM running on a Fedora 14 server/host, installed using virt-manager, pretty plain vanilla. I use it to compile binaries to run under RHEL/CentOS 5.n OS. I occasionally notice that when the VM gets paged out by the server, it takes several minutes to get it back in :-/ (see below). On the host, logged in to a shell through a terminal window, this A.M.: [wam at Q6600,

I am running Xen 3.0.1 with Gentoo for Dom0 and when I create a DomU with Debian, the kernel or system does not seem to recognize the volume I have created for swap on the DomU and will not mount it during boot or after. here is the disk section of the xen config for the DomU: disk = [ ''phy:xen-disks/disk-root,hda1,w'',''phy:xen-disks/disk-swap,hda2,w'' ]

git mv resume.c resumelib.c and the addition of a minimal resume.c, which calls resume() from resumelib produces a small standalone resume. happy to hear feedback on the needed kinit/Kbuild changes. resulting resume bin is small: ls -l /usr/lib/klibc/bin/resume -rwxr-xr-x 1 root root 2904 2006-07-11 02:11 /usr/lib/klibc/bin/resume it reduces busybox dependency of Debian initramfs-tools: if [ -e

Hi all, today we've encountered quite strange issues with memory allocation on one of our VPS running CentOS 6.2. So far I've been unable to determine what's causing it - hopefully someone here will know what's up. The VPS is a "small" machine - just 512MB of RAM, 1 CPU, running 6.2. with current kernel (2.6.32-220.4.2.el6.x86_64, but I've tried the

When a new system CentOS-4.4 is built the swap partition is always reversed... Note md3 below, the raidtab is OK, I have tried various raid commands to correct. swapoff -a raidstop /dev/md3 mkraid /dev/md3 --really-force swapon -a And then I get a proper ourput for /proc/mdstat, but when I reboot /proc/mdstat again reads as below, with md3 [0] [1] reversed. [root]# cat /proc/mdstat

Hey all, Had a power failure and subsequent ext3 disk corruptions. Attempting to fix, but not working. Its a 120 gig IDE disk, 3 partitions. /boot, /, and swap. Basically can't boot up since the box can't get to the system files in /usr/ or anything. So I'm booting off of a FC2 disk 1 in recovery mode and trying to fix the filesystem with e2fsck The boot partition cleaned up

The swapon label test has a side-effect, in that it creates a new partition. This causes the later failure of the list_partitions test. This change causes the swapon_label test to scrub /dev/sdb after the test, and then re-read the partition table. --- src/generator.ml | 4 +++- 1 files changed, 3 insertions(+), 1 deletions(-) diff --git a/src/generator.ml b/src/generator.ml index

I just upgraded a blade server via rsync from another server. Rebuilt the initrd. It boots fine... except that it won't turn on the swap partition. Several times, I've made sure swap was off, then mkswap -L SWAP-sda3 /dev/sda3, but when I do swapon -L SWAP-sda3, it complains it can't find the device for the label. The only thing I find while googling, other than redoing what I've

I just reinstalled Centos 7 on my Dell Inspiron 15 7570. This time I created a swap partitition that is 24 Gb in size since the machine has 16 Gb of memory. Still unable to hibernate with 'systemctl hibernate' which generates a message that a 'dependency on hibernate.target failed'. Typing swapon -s or cat /proc/swaps I see: /dev/dm-2 partititon 25161724 0 -1 free -m gives me:
