on boot hotplug tries to load the ieee1394 module on my system. The port in question is on an sb audigy. Reproducible: Always Steps to Reproduce: 1. recompile kernel with modular support for ieee stuff 2. boot 3. start hotplug Actual Results: This causes an oops: ieee1394: Host added: ID:BUS[0-00:1023] GUID[00023c00200083aa] Badness in kobject_get at lib/kobject.c:431 Call Trace: [<c022e0dc>] kobject_get+0x4c/0x50 [<c02846a8>] get_device+0x18/0x30 [<c0285323>] bus_for_each_dev+0x63/0xc0 [<f890861d>] nodemgr_node_probe+0x4d/0x130 [ieee1394] [<f89084e0>] nodemgr_probe_ne_cb+0x0/0x90 [ieee1394] [<f8908a79>] nodemgr_host_thread+0x179/0x1a0 [ieee1394] [<f8908900>] nodemgr_host_thread+0x0/0x1a0 [ieee1394] [<c0109289>] kernel_thread_helper+0x5/0xc Unable to handle kernel paging request at virtual address b828ec83 printing eip: b828ec83 *pde = 00000000 Oops: 0000 [#1] CPU: 0 EIP: 0060:[<b828ec83>] Not tainted EFLAGS: 00010282 EIP is at 0xb828ec83 eax: b828ec83 ebx: f8914c04 ecx: f754df9c edx: 00000000 esi: f8907ee0 edi: 00000000 ebp: f8906bb0 esp: f754df40 ds: 007b es: 007b ss: 0068 Process knodemgrd_0 (pid: 3443, threadinfo=f754c000 task=f7998040) Stack: c022e178 f8914c04 f8914be0 f8914be8 f8914b40 f7438044 c0285340 f8914c04 f754df9c f8914b8c 00000000 f743803c f754df9c f760d3d8 f754df9c f890861d f8914b40 f743803c f754df9c f89084e0 f7534000 f760d3d8 f7534000 f760d3d8 Call Trace: [<c022e178>] kobject_cleanup+0x98/0xa0 [<c0285340>] bus_for_each_dev+0x80/0xc0 [<f890861d>] nodemgr_node_probe+0x4d/0x130 [ieee1394] [<f89084e0>] nodemgr_probe_ne_cb+0x0/0x90 [ieee1394] [<f8908a79>] nodemgr_host_thread+0x179/0x1a0 [ieee1394] [<f8908900>] nodemgr_host_thread+0x0/0x1a0 [ieee1394] [<c0109289>] kernel_thread_helper+0x5/0xc Code: Bad EIP value. <6>eth0: Setting full-duplex based on MII #1 link partner capability of 45e1. blk: queue f7dd6a00, I/O limit 4095Mb (mask 0xffffffff) blk: queue f7dd6600, I/O limit 4095Mb (mask 0xffffffff) blk: queue f7dcaa00, I/O limit 4095Mb (mask 0xffffffff) svc: unknown version (3) request_module: failed /sbin/modprobe -- char-major-226-0. error = 256 Expected Results: inserted driver with no error.

this has been solved in more recent versions. 2.6.3_rc3 will hit portage soon. there is a patch at: http://dev.gentoo.org/~johnm/files this fixes the problem in the mean time, the updated patchset wasnt rolled out due to the liklyhood of rc3 being released. Please apply as follows: cd /usr/src/linux patch -p1 < /path/to/124_*.patch or upgrade to rc3. it should be available within 2 hours in portage. just waiting for mirrors to propogate :)
