[Xen-users] cx88_wakeup: 2 buffers handled (should be 1) - PCI/IRQ issues in domU
Hi, I''m trying to use a DVB-T PCI tuner card in domU. I''ve had this working without any problems in an old configuration of my Xen server, but it stopped working when I upgraded the system''s hardware (CPU and motherboard) and the Xen version (unstable from around May to testing from last week). The symptom is an endless stream of "cx88_wakeup: 2 buffers handled (should be 1)" messages in the guest. This is actually a known but rare issue, independently of Xen, caused when the system doesn''t respond to interrupts fast enough. But I''ve had this working in a domU before, so obviously there''s something in my current setup that creates interrupt issues... but what could it be - Xen setup? BIOS setup? Xen bug? Any ideas how to look for the cause? TIA, Itai _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
