I just got a crash while using cdparanoia (a cd ripper) on my PPro 180, running 2.2.10.
Here is what I could transcribe (manually):
Call trace: [<c012daee>] [<c012de34>] [c012e1a5>] [<c0109dd0>] Unable to handle NULL pointer dereference at virtual address 00000004 current->tss.cr3= 00101000, %cr3=00101000 *pde=00000000 oops: 0002 CPU 0 EIP 0010 [<c0121d75>] EFLAGS: 00010046 eax: c02c89c0 ebx: 00001eec ecx: ffffffff edx: 00000000 esi: 00003dd8 edi: c021394c ebp: 00000202 esp: c009ddfc ds: 0018 es: 0018 ss: 0018 Process init (pid: 1, process nr: 1, stackpage = c009d000
...
Here's my configuration: PPro 180 Mhz / 64 MB hda: Western Digital 3.2 GB (not mounted at time of crash) hdb: Mitsumi CD-R 8/4 under scsi emulation on /dev/scd0 (thhis is the cdrom I was using cdparanoia on when the crash happened) hdc: Quantum Fireball 13 GB (where / is) hdd: Panasonic 4x cdrom under scsi emulation on /dev/scd1 (don't know if it was mounted) two PCI NE2000 cards (doing ip forwarding) 1 SB 16 ISA PnP 1 SB PCI 64
Before the crash, the driver has been acting a bit strangely (work sometimes, sometimes doesn't). The crash occured exactly at the time I tried to stop (^C) cdparanoia. Also, I have had other problems on this machine which *might* be related:
1) What seems to be huge memory leaks in the kernel (I kill everything (X, nfs, smb, ...), but the system is still using ~30 Meg more memory (excluding cached data) than at boot and my system can hardly do anything). It happened twice under 2.2.9, it's too soon to know if 2.2.10 fixed it.
2) I've found the following oops in a log (2.2.9):
Unable to handle kernel paging request at virtual address 001bd016 current->tss.cr3 = 03790000, %cr3 = 03790000 *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[opl3:opl3_detect_R67481767+-18308987/5620] EFLAGS: 00010246 eax: c36b7300 ebx: 001bd016 ecx: 001bd016 edx: 00001606 esi: c0126884 edi: 0000020c ebp: c36b7300 esp: c3d25e5c ds: 0018 es: 0018 ss: 0018 Process ld (pid: 21339, process nr: 96, stackpage=c3d25000)
If you need more info, just tell me. Or if you think of anything I can try to find (reproduce) the bug.
