I've been trying [unsuccessfully :S] to get the kernel's pcmcia working. I woke up this morning and found the following oops: Unable to handle kernel NULL pointer dereference at virtual address 0000001b c01d4dca *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010296 eax: c84e9ec0 ebx: 00000000 ecx: c03560c8 edx: c376d140 esi: cbf7bbb4 edi: c376d000 ebp: 00000008 esp: cbf7bab4 ds: 0018 es: 0018 ss: 0018 Process kapm-idled (pid: 2, stackpage=cbf7b000) Stack: c376d070 cbf7bbb4 c376d000 c376d140 00000001 c03ae5cc 00000009 c376d140 c01d9041 c376d000 cb236400 c0367040 cbf7bc0b cbfe2940 000000ff 0000000c cbf7bb34 18b0ffff c0344c40 2000bb10 ffffff30 00000000 00000003 00001880 Call Trace: [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] Code: 80 7b 1b 00 0f 84 12 03 00 00 8b 4c 24 1c 83 b9 58 02 00 00 >>EIP; c01d4dca <===== Trace; c01d9041 Trace; c0344c40 Trace; c02190f1 Trace; c0219337 Trace; c022450b Trace; c021c05b Trace; c021bfc0 Trace; c021bf50 Trace; c021c1e8 Trace; c021c2a4 Trace; c02205ec Trace; c02199a9 Trace; c0219a2d Trace; c0219a96 Trace; c0219ac5 Trace; c0115841 Trace; c01158d5 Trace; c011082d Trace; c0110aa4 Trace; c0110b5b Trace; c0110bd2 Trace; c02cf0bc Trace; c011152a Trace; c010910f Trace; c0109118 Code; c01d4dca 00000000 <_EIP>: Code; c01d4dca <===== 0: 80 7b 1b 00 cmpb $0x0,0x1b(%ebx) <===== Code; c01d4dce 4: 0f 84 12 03 00 00 je 31c <_EIP+0x31c> c01d50e6 Code; c01d4dd4 a: 8b 4c 24 1c mov 0x1c(%esp,1),%ecx Code; c01d4dd8 e: 83 b9 58 02 00 00 00 cmpl $0x0,0x258(%ecx) if (ee_data[27] == 0) { /* No valid media table. */ 17a: 80 7b 1b 00 cmpb $0x0,0x1b(%ebx) 17e: 0f 84 12 03 00 00 je 496 } else if (tp->chip_id == DC21041) { 184: 8b 4c 24 1c mov 0x1c(%esp,1),%ecx 188: 83 b9 58 02 00 00 01 cmpl $0x1,0x258(%ecx) 18f: 0f 85 8b 00 00 00 jne 220 -d
