[CentOS-virt] domU shutdown with cx88 crashes dom0
Hi, I've got a big problem with a cx88 DVB card. It is passed through to a CentOS 5.3 domU (dom0 is CentOS 5.3 as well), but when I shutdown the domU, this happens: cx88[0]: mpeg risc op code error cx88[0]: mpeg - dma channel status dump cx88[0]: cmds: initial risc: 0xffffffff cx88[0]: cmds: cdt base : 0xffffffff cx88[0]: cmds: cdt size : 0xffffffff cx88[0]: cmds: iq base : 0xffffffff cx88[0]: cmds: iq size : 0xffffffff cx88[0]: cmds: risc pc : 0xffffffff cx88[0]: cmds: iq wr ptr : 0xffffffff cx88[0]: cmds: iq rd ptr : 0xffffffff cx88[0]: cmds: cdt current : 0xffffffff cx88[0]: cmds: pci target : 0xffffffff cx88[0]: cmds: line / byte : 0xffffffff cx88[0]: risc0: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: risc1: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: risc2: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: risc3: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 0: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 1: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 2: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 3: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 4: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 5: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 6: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 7: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 8: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq 9: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq a: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq b: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq c: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq d: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq e: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: iq f: 0xffffffff [ INVALID sol eol irq2 irq1 23 22 21 20 19 18 cnt1 cnt0 resync 14 13 12 count=4095 ] cx88[0]: fifo: 0x00186400 -> 0x187400 cx88[0]: ctrl: 0x001807c0 -> 0x180820 cx88[0]: ptr1_reg: 0xffffffff cx88[0]: ptr2_reg: 0xffffffff cx88[0]: cnt1_reg: 0xffffffff cx88[0]: cnt2_reg: 0xffffffff This loops forever eating every available cpu cycle. The dom0 becomes unusably slow until I manually destroy the domU. The domU runs 2.6.18-128.1.10.el5xen with video4linux-kmdl-2.6.18-128.1.10.el5xen-20090415-88.0.4.el5 (there are no video4linux-kmdls for the latest kernel yet). Manually unloading the modules before shutting down has no effect. Without video4linux-kmdl installed, everything works fine. I hope you can help me. Regards, Chris

Information missing? Regards, Chris
