Since approx. kernel 2.6.35 (kernel.org) I have been having a problem with
xfsdump(8) with my custom compiled kernels but not with the one that comes
with openSUSE. During a differential dump (1..9) it will lock up, become a
kernel stuck process that cannot be killed, while determining the files
that need to be dumped. This has not occurred with dump level zero nor with
the kernel as supplied from openSUSE. I have played with the kernel options
that seem relevant to xfs (a find for xfs as well as ACPI, etc.) and
nothing seems to effect the problem. Other than this, everything works fine
and the kernel has better performance and support in the areas that I
compile it for with respect to my hardware. I was hoping that you could
inform me as to what options for the kernel might cause this problem. Note
that a reboot or even an 'init 0 --- init 3' will clear the problem for at
least one more differential dump.

openSUSE: 11.4
CPU : AMD 64 AM2 socket
RAM: 4GB DDR2
Drives: SATA/3 Boot is a 650GB WD, /usr/local is a 1.5TB WD

Kernel: 3.1.4
I compile the kernel with the AMD64 optimization turned on.

Thank you!

If the kernel thread is really stuck, sysrq-D (or echo d > /proc/sysrq-trigger)
will show where the thread is; that'd at least provide some more concrete
information if the thread is really stuck somewhere.
