[Xen-devel] cpu.c BUG, Xen or hardware failure?
Hi! Today one of my domU is showing the following message at the xvc0 console: BUG: warning at /home/administrativo/xen-3.3.2/linux-2.6.18-xen.hg/kernel/cpu.c:53/unlock_cpu_hotplug() Call Trace: [<ffffffff80248c7a>] unlock_cpu_hotplug+0x3f/0x6c [<ffffffff802295b2>] sched_getaffinity+0x7e/0x90 [<ffffffff8024f281>] compat_sys_sched_getaffinity+0x1d/0x4a [<ffffffff8021ebda>] sysenter_do_call+0x1b/0x25 BUG: warning at /home/administrativo/xen-3.3.2/linux-2.6.18-xen.hg/kernel/cpu.c:53/unlock_cpu_hotplug() Call Trace: [<ffffffff80248c7a>] unlock_cpu_hotplug+0x3f/0x6c [<ffffffff802295b2>] sched_getaffinity+0x7e/0x90 [<ffffffff8024f281>] compat_sys_sched_getaffinity+0x1d/0x4a [<ffffffff8021ebda>] sysenter_do_call+0x1b/0x25 This can be the root of some weird problems with the domU... This is a hardware failure or Xen BUG?! Thanks, Thiago _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
This may be fixed by linux-2.6.18-xen.hg:931.

The "make prep-kernels" will get this version via mercurial when it arrives? Thanks! Thiago 2009/8/30 Keir Fraser <keir.fraser@eu.citrix.com>> This may be fixed by linux-2.6.18-xen.hg:931.
