Removing the module works with stock 2.4.12 [2.6.12? --adobriyan].
It works on stock 2.6.12, of course. Feel free to ask for additional information.
hrm, works for me. Can you test -mm2 and if it's still bad, send the .config? Thanks.
Ok, tested with 2.6.12-mm2 and it behaves the same. This is without any fireware device attached in case it matters: rmmod D 0FF7F724 0 4334 4225 (NOTLB) Call trace: [c000742c] __switch_to+0x48/0x70 [c029ec84] schedule+0x344/0x714 [c029f0cc] wait_for_completion+0x78/0x114 [c029e3dc] klist_remove+0x24/0x38 [c013742c] device_del+0x34/0xb8 [c01374c8] device_unregister+0x18/0x30 [c018c7a4] nodemgr_remove_ne+0x6c/0x88 [c018c7d4] __nodemgr_remove_host_dev+0x14/0x28 [c0137560] device_for_each_child+0x4c/0x74 [c018c810] nodemgr_remove_host_dev+0x28/0x6c [c0188f94] __unregister_host+0xdc/0xe0 [c0189b40] highlevel_remove_host+0x70/0xd8 [c0188868] hpsb_remove_host+0x60/0x8c [e2210fec] ohci1394_pci_remove+0x5c/0x288 [ohci1394] [c00e4f6c] pci_device_remove+0x60/0x64 I am attaching the .config.
