I don't use the SCSI card/drive for booting but the driver is compiled into my kernel, and reading from the drive seems OK. Booting -mm2 I get the following : scan_host_selected+0xdd/0xf0 [] scsi_scan_host+0x30/0x40 [] sym2_probe+0xef/0x140 [] do_simd_coprocessor_error+0x70/0xb0 [] sys_get_thread_area+0x10/0x140 [] pci_device_probe_static+0x52/0x70 [] __pci_device_probe+0x3c/0x50 [] pci_device_probe+0x2f/0x50 [] driver_probe_device+0x3b/0xb0 [] __driver_attach+0x0/0x60 [] __driver_attach+0x50/0x60 [] bus_for_each_dev+0x69/0x80 [] driver_attach+0x25/0x30 [] __driver_attach+0x0/0x60 [] bus_add_driver+0x88/0xc0 [] pci_device_shutdown+0x0/0x30 [] pci_register_driver+0x7d/0xa0 [] sym2_init+0x32/0x60 [] do_initcalls+0x2b/0xc0 [] init+0x99/0x1b0 [] init+0x0/0x1b0 [] kernel_thread_helper+0x5/0x10 Followed by many repeats of: BUG: atomic counter underflow at: [] blk_cleanup_queue+0xc1/0xd0 [] scsi_device_dev_release+0x139/0x190 [] device_release+0x5b/0x60 [] kobject_cleanup+0x98/0xa0 [] kobject_release+0x0/0x10 [] kref_put+0x45/0xd0 [] kobject_put+0x1f/0x30 [] kobject_release+0x0/0x10 [] scsi_alloc_sdev+0x1ae/0x1f0 [] scsi_probe_and_add_lun+0x6f/0x1f0 [] kobject_get+0x1a/0x30 [] scsi_scan_target+0xe3/0x170 [] scsi_scan_channel+0x9d/0xc0 [] scsi_scan_host_selected+0xdd/0xf0 [] scsi_scan_host+0x30/0x40 [] sym2_probe+0xef/0x140 [] do_simd_coprocessor_error+0x70/0xb0 [] sys_get_thread_area+0x10/0x140 [] pci_device_probe_static+0x52/0x70 [] __pci_device_probe+0x3c/0x50 [] pci_device_probe+0x2f/0x50 [] driver_probe_device+0x3b/0xb0 [] __driver_attach+0x0/0x60 [] __driver_attach+0x50/0x60 [] bus_for_each_dev+0x69/0x80 [] driver_attach+0x25/0x30 [] __driver_attach+0x0/0x60 [] bus_add_driver+0x88/0xc0 [] pci_device_shutdown+0x0/0x30 [] pci_register_driver+0x7d/0xa0 [] sym2_init+0x32/0x60 [] do_initcalls+0x2b/0xc0 [] init+0x99/0x1b0 [] init+0x0/0x1b0 [] kernel_thread_helper+0x5/0x10 Thanks, Yani
