Can you reproduce this issue with newer versions of .18 ? If so, please report the issue upstream on http://bugzilla.xensource.com/ Hi, The host has been un-xenified, so I can't run any tests. The Haupage drivers have also become more stable over time so this bug might not be reproducible. Cheers |
I am experiencing a kernel bug when running a Hauppauge Nova T500 Dual HDTV Tuner DVB card inside a Xen domain. I have seen the bug over a long period, close to a year now. It happens in xen-sources 2.6.18-xen-r7 and 2.6.20. It's been a while since I ran 2.6.16 but I believe it happened there as well. I'm not sure where to go from here. The DVB drivers are from media-tv/v4l-dvg-hg when using 2.6.18 and the included kernel modules in 2.6.20. Can this be a problem with the DVB driver even though the kernel spits out: "kernel BUG at arch/i386/mm/hypervisor.c" ? The following is the kernel output when the bug trips: ------------[ cut here ]------------ kernel BUG at arch/i386/mm/hypervisor.c:172! invalid opcode: 0000 [#1] SMP Modules linked in: mt2060 dvb_usb_dib0700 dib7000p dib7000m dvb_usb dvb_ core dib3000mc dibx000_common dib0070 CPU: 1 EIP: 0061:[<c010f53b>] Not tainted VLI EFLAGS: 00010282 (2.6.18-xen-r7 #2) EIP is at xen_pgd_pin+0x58/0x66 eax: ffffffea ebx: c969fe40 ecx: 00000001 edx: 00000000 esi: 00007ff0 edi: e64b4040 ebp: e6acec80 esp: c969fe40 ds: 007b es: 007b ss: 0069 Process cron (pid: 4551, ti=c969e000 task=c00eb030 task.ti=c969e000) Stack: 00000001 00057f8e 13dc8000 00013dc8 c06b72e2 c010c61f e64b4040 c010c64b e6acecb4 c0154a6e e69d2a00 00000000 e7bc6bc0 c07df514 e78003c0 c041de48 c00eb030 e6acec80 00000000 00000000 c07df570 e69d2a00 c0000000 c0365af1 Call Trace: [<c010c61f>] __pgd_pin+0x26/0x36 [<c010c64b>] mm_pin+0x1c/0x22 [<c0154a6e>] flush_old_exec+0x5b5/0x940 [<c041de48>] af_unix_init+0x3f/0x59 [<c0153f99>] kernel_read+0x32/0x43 [<c016f23a>] load_elf_binary+0x480/0x1430 [<c0135377>] __alloc_pages+0x4e/0x267 [<c0153cb0>] copy_strings+0x1b3/0x1bd [<c0153d56>] search_binary_handler+0x75/0x1ec [<c0155696>] do_execve+0x143/0x1b1 [<c0103250>] sys_execve+0x2a/0x72 [<c0104953>] syscall_call+0x7/0xb Code: 35 c0 a1 64 c6 42 c0 8b 14 90 81 e2 ff ff ff 7f 89 54 24 04 89 e3 b9 01 00 00 00 31 d2 be f0 7f 00 00 e8 09 1e ff ff 85 c0 79 08 <0f> 0b ac 00 97 1d 36 c0 83 c4 0c 5b 5e c3 56 89 c2 c1 ea 0c 53 EIP: [<c010f53b>] xen_pgd_pin+0x58/0x66 SS:ESP 0069:c969fe40 Reproducible: Sometimes Steps to Reproduce: Record tv, change channels, record some more. Some times takes a few hours to trigger the bug. Actual Results: The domU crashes and must be "rebooted". The domU will not be able to use the Haupage card again without a proper dom0 reboot.
