[rhts] ia64: hvm guests cause large amounts of soft lockup warnings
Last modified: 2009-07-09 10:28:41 EDT
Description of problem:
When running our kernel tier 1 tests, we are noticing large amounts of
soft lockup warnings to the point our tests timeout and fail. Only recently
we have noticed more and more of these failures.
Some examples are:
Checking dmesg for specific failures!
BUG: soft lockup - CPU#1 stuck for 10s! [rhts-submit-log:32765]
BUG: soft lockup - CPU#1 stuck for 10s! [avahi-daemon:2233]
BUG: soft lockup - CPU#1 stuck for 10s! [events/1:9]
BUG: soft lockup - CPU#0 stuck for 10s! [kjournald:379]
End of log.
The following links show the failures for kernel-2.6.18-151.el5
Look through my testsuite history, kernel-2.6.18-146.el5 seemed to have
expected problems of only rpciod soft lockups (which has been normal for a
while), kernel-2.6.18-147.el5 failed to installed, kernel-2.6.18-148.el5 had
numerous softlockup failures which were _not_ expected.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run a kernel tier1 testsuite and notice how only hvm guests have issues
Is this still a problem, or have these messages gone away? I seem to remember some changed in 5.4 that fixed this particular problem, but my memory is fuzzy. DonZ?
Things have quieted down recently and I have not seen the volume of softlockups as I did in the past.
So if you want to close this as fixed in CURRENTRELEASE or something, I am ok with that. If that problem pops up again, I know where to find you. :-)
Haha. OK, will do, and as always, feel free to open another bug :).
