Actually, I'll be thrilled if this turns out to be a known issue. But I've searched on it forever, and although I've found some information, I've not found a definite fix. Possibly my fault, but this is driving me nuts. System: Asus P5N32E MB, Intel Quad Core; on SATA: two HDs, SATA Pioneer DVD-RW; on PATA: Plextor CDRW, one HD. (Can send more info of course.) Kernel is 2.6.23.9 on Fedora 8. [root@rghquad lyxsvn]# lsmod | grep ata pata_amd 20293 2 pata_pdc2027x 17477 0 sata_nv 25157 6 ata_generic 14405 0 libata 114673 4 pata_amd,pata_pdc2027x,sata_nv,ata_generic scsi_mod 145657 5 sr_mod,sg,usb_storage,libata,sd_mod The issue concerns locks ups and other errors that seem to be focused on the optical drives. I'm getting this kind of error: Jan 16 01:33:19 rghquad kernel: ata7.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen Jan 16 01:33:19 rghquad kernel: ata7.01: cmd a0/00:00:00:00:20/00:00:00:00:00/b0 tag 0 cdb 0x0 data 0 Jan 16 01:33:19 rghquad kernel: ata7: soft resetting port Jan 16 01:33:19 rghquad kernel: ata7.01: configured for MWDMA2 Jan 16 01:33:19 rghquad kernel: ata7: EH complete repeatedly, sometimes with the Plextor, sometimes with the Pioneer. But then things sometimes get worse: Jan 16 01:36:22 rghquad kernel: sr1: CDROM (ioctl) error, command: <6>ata7: EH complete Jan 16 01:36:22 rghquad kernel: __journal_remove_journal_head: freeing b_committed_data Jan 16 01:36:22 rghquad kernel: __journal_remove_journal_head: freeing b_frozen_data Jan 16 01:36:22 rghquad kernel: __journal_remove_journal_head: freeing b_committed_data and it seems as if the whole ATA system locks up. The main drive gets reset to read-only, and, well, things are not then good. The fact that this sometimes happens on SATA and sometimes on PATA suggests its not a cable issue. (That particular case was the Plextor.) Is it worth trying a larger PS? I believe I have 450W in this system. Any help or suggestions more than welcome. Best, Richard Heck
