Hi,
I am observing a filesystem lockup with XFS on a CONFIG_PREEMPT_RT patched kernel. I have currently only triggered it using dpkg. Dave Chinner on the XFS mailing list suggested that it was a rt-kernel workqueue issue as opposed to a XFS problem after looking at the kernel messages.
$ uname -a Linux vpc5 3.10.24-rt22abs #15 SMP PREEMPT RT Tue May 13 14:42:22 PDT 2014 x86_64 GNU/Linux
The only modification to the kernel besides the RT patch is that I have applied tglx's "genirq: Sanitize spurious interrupt detection of threaded irqs" patch.
Any ideas on what could be wrong?
Is there any information that I can pull before I reboot the machine that would be useful? I have the output of triggering sysrq with l and t if that would be useful. Attached is the kernel blocked task message output.
Thanks, Austin [unhandled content-type:application/octet-stream] | |
