Unfortunately, when using a kernel from the 2.4 series, I am still not able to use my USB Drive. Just as a reminder, I was having problems with various 2.4 kernels and decided to try a 2.6 kernel (2.6.0-test9). Since I also had problems there (with data available at http://www.ime.usp.br/~rbrito/usb/), I decided to go back to a 2.4 kernel, 2.4.23-pre9 + the current packet writing patch. I got many errors when I booted my system. Then, I tried playing with the hotplug scripts (disabling hotplug). And I got an Oops. The decoded oops is here: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ksymoops 2.4.9 on i686 2.4.23-pre9-pkt-1.

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. kernel BUG at slab.c:815! invalid operand: 0000 CPU: 0 EIP: 0010:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 eax: 00000000 ebx: c7feaae0 ecx: c7feaa6c edx: c7feaa6c esi: c7feaa66 edi: c8899a2a ebp: c027b1d8 esp: c368deec ds: 0018 es: 0018 ss: 0018 Process modprobe.moduti (pid: 1259, stackpage=c368d000) Stack: fffffffc 0000001c fffffff4 00000001 00000001 ffffffea c88994b5 c8899a1c 0000003c 00000010 00000000 00000000 00000000 c8895000 c0116935 c889ab60 0808c6e0 00005a90 00000060 00000060 00000004 c61a3d00 c393a000 c38f4000 Call Trace: [] [] [] [] [] [] Code: 0f 0b 2f 03 62 fb 1f c0 8b 12 81 fa a4 78 22 c0 75 d3 8d 43 >>EIP; c012a6f3 <===== >>ebx; c7feaae0 <_end+7d4f0c8/859a648> >>ecx; c7feaa6c <_end+7d4f054/859a648> >>edx; c7feaa6c <_end+7d4f054/859a648> >>esi; c7feaa66 <_end+7d4f04e/859a648> >>edi; c8899a2a <[uhci].text.end+425/13db> >>ebp; c027b1d8 >>esp; c368deec <_end+33f24d4/859a648> Trace; c88994b5 <[uhci]uhci_hcd_init+69/f4> Trace; c8899a1c <[uhci].text.end+417/13db> Trace; c0116935 Trace; c889ab60 <[uhci]__module_license+45/85> Trace; c8895060 <[uhci]uhci_show_td+0/198> Trace; c0106e93 Code; c012a6f3 00000000 <_EIP>: Code; c012a6f3 <===== 0: 0f 0b ud2a <===== Code; c012a6f5 2: 2f das Code; c012a6f6 3: 03 62 fb add 0xfffffffb(%edx),%esp Code; c012a6f9 6: 1f pop %ds Code; c012a6fa 7: c0 8b 12 81 fa a4 78 rorb $0x78,0xa4fa8112(%ebx) Code; c012a701 e: 22 c0 and %al,%al Code; c012a703 10: 75 d3 jne ffffffe5 <_EIP+0xffffffe5> Code; c012a705 12: 8d 43 00 lea 0x0(%ebx),%eax 1 warning issued.
