kernel: panic: softdep_sync_buf: Unknown type jnewblk

[António Trindade]

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.
