The oops (processed by ksymoops) is appended. uhci works OK. Regards, Petr ksymoops 2.4.3 on i686 2.4.10. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.10/ (default) -m /boot/System.map-2.4.10 (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options. chazelle login: Unable to handle kernel paging request at virtual address ffffffdc cc902471 *pde = 00001063 Oops: 0000 CPU: 0 EIP: 0010:[] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010203 eax: 00000000 ebx: c7dd746c ecx: 00000000 edx: c02e9400 esi: 00000000 edi: c7dd73c0 ebp: c7df3000 esp: c0281eec ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 0, stackpage=c0281000) Stack: c7dd746c c7dd73c0 c1322d60 00000000 00000010 c7dea120 00000000 00000001 cc9025f9 c1322d60 c7dd73c0 00000000 c7dd746c c1322d60 00000000 00000000 00000000 c011ad8f 00000000 cc90284d c1322d60 c7dd73c8 ca905360 04000001 Call Trace: [] [] [] [] [] [] [] [] [] [] [] [] [] Code: 8b 46 dc 8d 6e d8 a9 00 00 80 00 74 39 25 ff ff 7f ff 89 46 >>EIP; cc902470 <[usb-uhci]process_iso+64/184> <===== Trace; cc9025f8 <[usb-uhci]process_urb+68/1fc> Trace; c011ad8e Trace; cc90284c <[usb-uhci]uhci_interrupt+c0/120> Trace; c0107d0e Trace; c0107e6e Trace; c0105150 Trace; c0105150 Trace; c0105150 Trace; c0105150 Trace; c0105172 Trace; c01051d8 Trace; c0105000 <_stext+0/0> Trace; c0105026 Code; cc902470 <[usb-uhci]process_iso+64/184> 00000000 <_EIP>: Code; cc902470 <[usb-uhci]process_iso+64/184> <===== 0: 8b 46 dc mov 0xffffffdc(%esi),%eax <===== Code; cc902472 <[usb-uhci]process_iso+66/184> 3: 8d 6e d8 lea 0xffffffd8(%esi),%ebp Code; cc902476 <[usb-uhci]process_iso+6a/184> 6: a9 00 00 80 00 test $0x800000,%eax Code; cc90247a <[usb-uhci]process_iso+6e/184> b: 74 39 je 46 <_EIP+0x46> cc9024b6 <[usb-uhci]process_iso+aa/184> Code; cc90247c <[usb-uhci]process_iso+70/184> d: 25 ff ff 7f ff and $0xff7fffff,%eax Code; cc902482 <[usb-uhci]process_iso+76/184> 12: 89 46 00 mov %eax,0x0(%esi) <0>Kernel panic: Aiee, killing interrupt handler! 1 warning issued.
