[Xen-devel] Re: kernel BUG at arch/x86/xen/mmu.c:1860!

[Joerg Stephan <ml@xxxxxxxxxxx>]

Hey guys,

i just wanne report that our debian squeeze xen machines are also 
influenced by this bug, and we tried the workaround with the debug option 
by building our own
linux-image-2.6.32-5-xen-amd64_2.6.32-31_amd64.deb

but this isnt a workaround really, we tested it on an 40 vmachines dom0 
and it just dont work, of course the lvm works but the machine is slow as 
hell and runs into several kernel errors within a few hours
[46566.052925] BUG: soft lockup - CPU#0 stuck for 61s! [qemu-dm:6292]

in this case xentop shows an 500% CPU usage by the dom0, we experience an 
85%st value.
So, i think this should be fixed soon, so what is the status of the issue?

Best whishes

Joerg
