Re: [Xen-devel] irqbalance segfaults

["Olivier B." <xen.list@xxxxxxxxx>]

Hi,

it's an irqbalance bug, because of the directory /proc/irq/0 which doesn't 
exists under Xen PV.
See the Debian report about that : 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=517183

Ana will package the fix soon for Debian Squeeze (backports ?), but which 
distribution are you using ?
