Eric W. Biederman 78b7611c4a msi: mask the msix vector before we unmap it ... With these two lines in the reverse order the drives/block/ccis.c was oopsing in msi_free_irqs. Silly us calling writel on an area after we unmap it. BUG: unable to handle kernel paging request at virtual address f8b2200c printing eip: c01e9cc7 *pdpt = 0000000000003001 *pde = 0000000037e48067 *pte = 0000000000000000 Oops: 0002 [#1] SMP Modules linked in: cciss ipv6 parport_pc lp parport autofs4 i2c_dev i2c_core sunrpc loop dm_multipath button battery asus_acpi ac tg3 floppy sg dm_snapshot dm_zero dm_mirror ext3 jbd dm_mod ata_piix libata mptsas scsi_transport_sas mptspi scsi_transport_spi mptscsih mptbase sd_mod scsi_mod CPU: 1 EIP: 0060:[<c01e9cc7>] Not tainted VLI EFLAGS: 00010286 (2.6.22-rc2-gd2579053 #1) EIP is at msi_free_irqs+0x81/0xbe eax: f8b22000 ebx: f71f3180 ecx: f7fff280 edx: c1886eb8 esi: f7c4e800 edi: f7c4ec48 ebp: 00000002 esp: f5a0dec8 ds: 007b es: 007b fs: 00d8 gs: 0033 ss: 0068 Process rmmod (pid: 5286, ti=f5a0d000 task=c47d2550 task.ti=f5a0d000) Stack: 00000002 f8b72294 00000400 f8b69ca7 f8b6bc6c 00000002 00000000 00000000 00000000 00000000 00000000 f5a997f4 f8b69d61 f7c5a4b0 f7c4e848 f7c4e848 f7c4e800 f7c4e800 f8b72294 f7c4e848 f8b72294 c01e3cdf f7c4e848 c024c469 Call Trace: [<f8b69ca7>] cciss_shutdown+0xae/0xc3 [cciss] [<f8b69d61>] cciss_remove_one+0xa5/0x178 [cciss] [<c01e3cdf>] pci_device_remove+0x16/0x35 [<c024c469>] __device_release_driver+0x71/0x8e [<c024c56e>] driver_detach+0xa0/0xde [<c024bc5c>] bus_remove_driver+0x27/0x41 [<c01e3ef3>] pci_unregister_driver+0xb/0x13 [<f8b6a343>] cciss_cleanup+0xf/0x51 [cciss] [<c0139ced>] sys_delete_module+0x110/0x135 [<c0104c7a>] sysenter_past_esp+0x5f/0x85 Here's a patch that just reverses the 2 lines of code as Eric suggests.
