I think I have an answer finally. Bad drive. I've plugged a new sata controller in, and I get the following from it: [ 1581.172316] ata15: translated ATA stat/err 0x01/04 to SCSI SK/ASC/ASCQ 0xb/00/00 [ 1581.172325] ata15: status=0x01 { Error } [ 1581.172333] ata15: error=0x04 { DriveStatusError } I assume that means the drive is at fault. (one system lock up later...) shortly after I wrote the above this appeared in dmesg: Sep 3 16:33:59 natasha kernel: [ 1679.334788] ------------[ cut here ]------------ Sep 3 16:33:59 natasha kernel: [ 1679.334864] WARNING: at drivers/ata/libata- core.c:4910 __ata_qc_complete+0x5a/0xe1 [libata]() Sep 3 16:33:59 natasha kernel: [ 1679.334870] Hardware name: GA-MA790FXT-UD5P Sep 3 16:33:59 natasha kernel: [ 1679.334874] Modules linked in: fuse raid0 kvm_amd kvm powernow_k8 cpufreq_conservative cpufreq_stats cpufreq_userspace cpufreq_powersave nfsd exportfs nfs lockd fscache nfs_acl auth_rpcgss sunrpc bridge stp ext4 jbd2 crc16 md_mod it87 hwmon_vid adt7473 firewire_sbp2 loop snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_midi snd_rawmidi snd_seq_midi_event amd64_edac_mod snd_seq edac_core snd_timer snd_seq_device evdev snd soundcore i2c_piix4 snd_page_alloc i2c_core parport_pc parport wmi processor button ext3 jbd mbcache dm_mod usbhid hid sd_mod ata_generic pata_jmicron crc_t10dif atiixp firewire_ohci mvsas firewire_core crc_itu_t libsas scsi_transport_sas ohci_hcd ide_pci_generic ehci_hcd ide_core ahci libata scsi_mod r8169 mii floppy thermal fan thermal_sys [last unloaded: scsi_wait_scan] Sep 3 16:33:59 natasha kernel: [ 1679.334995] Pid: 0, comm: swapper Tainted: G W 2.6.31-rc5 #1 Sep 3 16:33:59 natasha kernel: [ 1679.335001] Call Trace: Sep 3 16:33:59 natasha kernel: [ 1679.335006] [] ?
