kernel: panic: softdep_sync_buf: Unknown type jnewblk
Cheers. I recently updated my system to FreeBSD-9.0 and activated softupdate journaling for a number of file systems (name /home, /var, /usr). Since then I have been experiencing kernel panics: kernel: panic: softdep_sync_buf: Unknown type jnewblk Yesterday, Jan 26th, I got 6 (six) automatic reboots due to these kernel panics. I have now disabled softupdates journaling in the hope that the panics disappear. I am sorry for not providing more information about the panic, but I'll gladly try to gather more info if instructed how to.

Usually you want to use your swap device. You should also boot into single user mode and do 'fsck -y' to make sure that the file systems are actually clean. There have been problems reported where SU+J doesn't recover fully after a crash, which leads to the kinds of instability you're reporting. hth, Doug -- It's always a long day; 86400 doesn't fit into a short. Breadth of IT experience, and depth of knowledge in the DNS. Yours for the right price. :) http://SupersetSolutions.com/

kernel: panic: softdep_sync_buf: Unknown type jnewblk
Hi. I'm pretty sure this will be considered almost as spam, but I reactivated SU+J a day and half ago and it still did not panic. However, I also activated dumpdev, so I'll be prepared to provide additional information in case of a panic.

kernel: panic: softdep_sync_buf: Unknown type jnewblk
Hi!
After a few days, I finally got a kernel panic like the one I reported earlier.
I attach the file info.0. I'm not attaching the vmcore.0 and core.txt.0
files, because they are over 100MB in size. If needed, they can be downloaded
from http://trindade.myphotos.cc/crash/vmcore.0.gz and
http://trindade.myphotos.cc/crash/core.txt.0.
I remind you that I am not using snapshots, at least conscientiously.
Hope this helps diagnosing the problem.
Meanwhile I deactivated SU+J again and reverted back to plain old SU.
Best regards.
