Hi, currently I'm developping a small kernel module for a hardware (which was developped by a friend of mine), which is supposed to load a firmware onto a PCI-card.
The development is done together with the friend, who's developping the firmware. We tried the following: He compiled a kernel-independent object (containing the firmware) on his system using kbuild (Dual-AthlonMP, SuSE 8.2 with kernel.org-kernel 2.6.3, module-init-tools 0.9.14-pre2, gcc 3.3.1, ld 2.14.90.0.5 20030722). Afterwards I tried to link it to my kernel-module (using the same kbuild makefile with firmware.o_shipped) on my machine (Fedora2, 2.6.5-3.1smp, module-init-tools 3.0-pre10, gcc 3.3.3, ld 2.15.90.0.3 20040415).
This is what happened:
Unable to handle kernel paging request at virtual address 82d90700 printing eip: 02135657 *pde = 00000000 Oops: 0002 [#1] PREEMPT SMP CPU: 1 EIP: 0060:[<02135657>] Not tainted EFLAGS: 00010246 (2.6.5-3.1smp) EIP is at module_unload_init+0xa/0x4d eax: 82d90700 ebx: 82c2387c ecx: 82d8f600 edx: 00000000 esi: 82c38f33 edi: 82c40027 ebp: 000005f0 esp: 763c3f38 ds: 007b es: 007b ss: 0068 Process insmod (pid: 1812, threadinfo=763c2000 task=7f3c60b0) Stack: 02136dc0 7864cc40 8282a000 00000000 82d8f600 00000000 00000000 00000000 00000000 00000000 0000000b 00000000 00000010 00000000 00000000 00000009 00000025 00000024 00000026 82c3829c 82c23727 82a94000 0856a008 763c3fc4 Call Trace: [<02136dc0>] load_module+0x53e/0x7fa [<021370da>] sys_init_module+0x5e/0x293 Code: 89 81 00 11 00 00 89 81 04 11 00 00 89 c8 c7 80 00 01 00 00 What puzzles me, is that I don't see any of my code in the calltrace. I had a look into the kernel-code and it seems to crash, before it even jumps into my code. What am I missing? By the way, everything works fine, if I compile the entire module on my machine. Some more testing showed, that we do also expierence a crash, if we do everything vice-versa. Regards, Michael
