Okay, I can't exactly reproduce the orignal panic (I think -- these might all be related), but here's another cdparanoia panic. I am using ATAPICAM, which I vaguely remember has caused some issues with other people. Note that this ocurred after I let bgfsck run its course. First off, a 'dmesg | grep ata1': ata1: at 0x170 irq 15 on atapci0 acd0: CDRW <SONY CD-RW CRX230E> at ata1-master PIO4 acd1: DVDROM <Pioneer DVD-ROM ATAPIModel DVD-120S> at ata1-slave PIO4 cd0 at ata1 bus 0 target 0 lun 0 cd1 at ata1 bus 0 target 1 lun 0 Now the actual panic: Fatal trap 12: page fault while in kernel mode cpuod = 0; apic id = 00 fault virtual address = 0xc1cad220 fault code = supervisor read, page not present instruction pointer = 0x8:0xc049a4a9 stack pointer = 0x10:0xd42bac74 frame pointer = 0x10:0xd42baca8 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 26 (irq15: ata1) kernel: type 12 trap, code=0 Stopped at ata_pio_read+0x64: repe insw %dx,%es:(%edi) db> examine ata_pio_read+0x64: eb6d66f3 db> trace ata_pio_read(c1ca5168,12,52e19674,d42bacdc,12) at ata_pio_read+0x64 ata_generic_interrupt(c1a7d600,0,0,0,0) at ata_generic_interrupt+0x473 ithread_loop(c19c2400,d42bad48,0,0,c19c2400) at ithread_loop+0x19c fork_exit(c05217c3,c19c2400,d42bad48) at fork_exit+0x7a fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xd42bad7c, ebp = 0 --- db> reset Me being a n00b, I have no idea what's going on. But I /do/ know that I can reliably produce a panic while ripping this CD. - Damian
