--- Comment #20 from Jan Beulich
I've applied that patch to kernel 3.16.7-21-xen on all four guests - sofar I cannot reproduce the problem. I'll leave it to run for a while and see if it changes.
Just to be certain - this was with the patch, but without the command line option based workaround in place? (The patch indeed contains one change that might improve behavior.) (In reply to Per Jessen from comment #19)
Created attachment 633352 [details] BUG: soft lockup - CPU#0 stuck for 23s
On one of my reboots while attempting to reproduce, one of the guests kept getting this error. I have seen this on physical machines before, but never on a xen guest.
Sadly you cut off too much from the log - right before the softlockup there was some kind of crash in xenblk.ko, and without seeing the call trace and register state (and perhaps also holding the module binary in hands to disassemble it) I can't tell whether that's related to the issue here (including the debugging patch) or whether it's something unrelated. -- You are receiving this mail because: You are on the CC list for the bug.
