I have a Dell 6650 running whatever the latest xen server image is (and
I run update/upgrade/dist-upgrade frequently). One DomU locks up pretty
regularly with "BUG: soft lockup - CPU#1 stuck for 11s!", usually during
large file transfers. DomU Kernel version is 2.6.24-19. The bug
*requires* destroying the DomU and restarting it.
Its pretty clear after reading many bug reports about this that it is in
the Kernel somewhere (and the kernel team has responded by changing
their policy about bug reporting). It is clearly NOT hardware or
application specific, as this is reported on many platforms and appears
to not have a consistent trigger.
Potentially, this is related to SMP, or PAE, although I find that
listing these as an area of issue is an easy scapegoat, even if it may
Id really like someone who KNOWS what this bug is caused by to provide a
definitive answer somewhere that can be seen by the public, and if
possible provide a workaround or targeted date for release of fix.
