Hi Bino, Fiddling with the lpfc driver on 2.6.20-rc4, shortly after booting, I attempted to rmmod the lpfc module and got a crash: io-raiders:~ # rmmod lpfc cpu 0x0: Vector: 300 (Data Access) at [c0000003c86075a0] pc: d0000000008d0988: .lpfc_free_sysfs_attr+0x1c/0x58 [lpfc] lr: d0000000008c458c: .lpfc_pci_remove_one+0x3c/0x278 [lpfc] sp: c0000003c8607820 msr: 9000000000009032 dar: 11c0 dsisr: 40000000 current = 0xc0000003bf4b4c80 paca = 0xc000000000674080 pid = 12977, comm = rmmod [ 3005.329608] ------------[ cut here ]------------ at which point the system locked up hard (I was expecting it to go into xmon).
