Re: [Xen-devel] irq 17: nobody cared (try booting with the "irqpoll" option)
Hi,
I know it''s a time since this question was posted and treated the
last
time, but I have quite the same problem, only its IRQ #18 and some other
pci devices, but it''s also a dom-u ("asterisk") with some
devices moved
there 2xISDN and 1 soundcard. The problem halts the whole system (also
the dom-0 ("powerless")), hard reboot is needed. This happens some
hours
after the dom-u (asterisk) is started. I''m right now trying the
noirqdebug workaround.
I think this occors since I move the soundcard into the asterisk
dom-u. I''d really be happy to keep it in the dom-0, but I
don''t see a
way to let the dom-u access it. I couldn''t find a virtual sound card
for
xen.
I would be grateful for any help.
