Default Bug#620216: linux-image-2.6.38-1-686: kernel hangs with XFS

Package: linux-2.6
Version: 2.6.38-1
Severity: important

Since the big XFS refacturing, kernels tend to hang on one particular machine. It is not a hardware problem, since the very same machine works flawlessly with the very same configuration, by just using an older (<=2.6.26) kernel.

Especially bad in this respect is the latest 2.6.38 as given in the email subject: The problem appears right after the reboot. I am filing this bug report on linux-image-2.6.37-1-686 which also shows hangs but only 1-2 times per week.

In order to isolate this bug, I am attending the kernel log for two distinct hangs (with a reboot in between) and disk information. I suspect that the problem occurs only on special types of disks, as I run almost the same configuration on multiple machines (same kernel, XFS formatted disks with the same XFS format version, same partitioning, etc.) without having any problems.

If you need any more info, I will be more than glad to help.

Best,
Thomas

Default Bug#620216: linux-image-2.6.38-1-686: kernel hangs with XFS

I suspect that the problem occurs only on special types of disks, as I run almost the same configuration on multiple machines (same kernel, XFS formatted disks with the same XFS format version, same partitioning, etc.) without having any problems.

I remember seeing a quite similar hang on 2.6.38 on a xftest run. please submit upstream on bugzilla.kernel.org
and let us know the bug nr.

thank you.
