Investigating (although I suspect this is fixed in more recent kernels, will try to get one into rawhide) I haven't this one yet... could you please try with trident.c from a recent 2.4 or 2.6 kernel? |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.5-0.2.9 i686; en-US; rv:0.9) Gecko/20010507 Description of problem: If you play something with the sound card (say an .mp3), the kernel oops. How reproducible: Always Steps to Reproduce: 1. Install the new rawhide kernel (kernel-2.4.5-0.2.9.i686) on a freshly installed RH 7.1 with all the updates. 2. Play something, let's say mpg123 asong.mp3 Actual Results: Nothing is played, mpg123 exits coredumpung, or saying "broken pipe", and this appears in dmesg <1>Unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c0115b6a *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[<c0115b6a>] EFLAGS: 00010086 eax: c703f318 ebx: 00000000 ecx: c1ccbf34 edx: c1ccbf2c esi: 00000282 edi: 00000000 ebp: c703f290 esp: c1ccbf20 ds: 0018 es: 0018 ss: 0018 Process esd (pid: 1743, stackpage=c1ccb000) Stack: c703f30c c1cca000 c0105c0b 00000001 c1cca000 c703f318 00000000 c6aa93e0 ffffffea c0105d70 c703f30c c703f280 c6aa9400 c8092ead 00000000 c1ccbf4c c703f280 00000000 00000000 c6aa93e0 ffffffea 00000000 00001000 c0133d26 Call Trace: [<c0105c0b>] [<c0105d70>] [<c8092ead>] [<c0133d26>] [<c0106f8f>] Code: 89 0b 56 9d 5b 5e c3 eb 0d 90 90 90 90 90 90 90 90 90 90 90 Expected Results: Just hear something...
