Currently, I can cat the file without an oops, but on a previous boot, the following oops came up when catting the file. Exact output from /proc/ioports is attached (some 8-bit garbage), as well as lsmod output. Let me know if further data is needed. I suspect that this is a problem in one of the drivers I am using, but how do I track down which one it is (since the name is not there)? Thanks, -Chris printing eip: c01a123a Oops: 0000 [#1] CPU: 0 EIP: 0060:[] Not tainted EFLAGS: 00010297 EIP is at vsnprintf+0x31a/0x450 eax: cca060f5 ebx: 0000000a ecx: cca060f5 edx: fffffffe esi: c3e7f10d edi: 00000000 ebp: c45bdec0 esp: c45bde88 ds: 007b es: 007b ss: 0068 Process cat (pid: 1661, threadinfo=3Dc45bc000 task=3Dc44a9340) Stack: c3e7f106 c3e7ffff 0000038b 00000000 00000010 00000004 00000002 0000= 0001=20 ffffffff ffffffff c3e7ffff c32971e0 00000000 c0241301 c45bdedc c016= 7426=20 c3e7f101 00000eff c024131a c45bdef8 c76fc580 c45bdf04 c011cf64 c329= 71e0=20 Call Trace: [] seq_printf+0x36/0x60 [] do_resource_list+0x64/0xa0 [] ioresources_show+0x4b/0x70 [] seq_read+0xef/0x300 [] vfs_read+0xaa/0x130 [] sys_read+0x3f/0x60 [] syscall_call+0x7/0xb =20 Code: 80 38 00 74 07 40 4a 83 fa ff 75 f4 29 c8 83 e7 10 89 c3 75=20 <6>note: cat[1661] exited with preempt_count 1 --kvUQC+jR9YzypDnK Content-Type: text/plain;
