Thanks for the report. I've not seen this before, will see if I can recreate in your environment (2.6.33.2). Just to be clear, "smooth and stable" includes the assigned device working fine in the guest? Hi Chris, yes indeed - the attached device in the windows VM is working without glitches. The device itself is an ISDN board and raises an IRQ every 125usec. I've u need any kind of additional information (e.g. the kernel config or traces) please let me know. In addition I will try some other PCI devices to check if this issue is somehow related to the specific behavior of the ISDN board...

Great, thanks. * bugzilla-daemon@bugzilla.kernel.org (bugzilla-daemon@bugzilla.kernel.org) wrote: > yes indeed - the attached device in the windows VM is working without > glitches. > The device itself is an ISDN board and raises an IRQ every 125usec. > > I've u need any kind of additional information (e.g. the kernel config or > traces) please let me know.

Hi Chris, it took some time, but now I can confirm that the same bug will occur on a win XP x86 VM with a soundcard (CreativeLabs SBlive! 5.1) attached. The sound output from the VM is fine but frequently the usual bug report is printed to the syslog. Therefore I assume that you should be able to reproduce this problem without the need for special hardware like my ISDN board:-) Best regards ralf Should be fixed by commit 46a47b1ed118cd in 2.6.34. |
