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


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
