[Xen-devel] Cannot bind IRQ 2 to guest. In use by ''cascade''.
Xen version 3.0-devel (nic@localdomain) (gcc version 3.3.5 (Debian
1:3.3.5-13)) Fri Oct 14 10:41:30 NZDT 2005
Latest ChangeSet: Fri Oct 14 03:26:44 2005 +0100 7369:92c6021f23e4
[....]
(XEN) Scrubbing Free RAM: .........................................done.
(XEN) *** Serial input -> DOM0 (type ''CTRL-a'' three times
to switch
input to Xen).
(XEN) (file=irq.c, line=224) Cannot bind IRQ 2 to guest. In use by
''cascade''.

What exactly is this for?
There doesn''t seem to be a IRQ 2 in /proc/interrupts
nic@wuwei:~$ cat /proc/interrupts

That message usually comes out when domain0 is probing for an irq by trying to bind to every irq in the system. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
