Hey all, I''ve just encountered the following on a rather busy virtual machine: BUG: warning at /usr/src/redhat/BUILD/xen-3.4.1/linux-2.6.18/kernel/cpu.c:53/unlock_cpu_hotplug() Call Trace: [<ffffffff80247679>] unlock_cpu_hotplug+0x3c/0x6d [<ffffffff802260aa>] sched_getaffinity+0x7e/0x95 [<ffffffff802260e7>] sys_sched_getaffinity+0x26/0x55 [<ffffffff80209302>] tracesys+0xab/0xb5 This is on a Dell PowerEdge 1950 w/ Xen 3.4.1, Kernel 2.6.18.8 (changeset 928 from linux-2.6.18-xen.hg), x86_64 Hypervisor and x86_64 dom0. Perhaps the patch outlined in http://lkml.org/lkml/2007/2/16/4 should be applied to the linux-2.6.18-xen.hg tree?

Forgot to specify, the domU on which this kernel message appeared is also x86_64.

Keir, I take it linux-2.6.18-xen.hg changeset 931 was applied to fix this bug? I''ll test it out this week.
