But I have been having extensive problems for quite some time now. Do you get these timeouts when using optical drives? That's what seems to trigger it in my case: If I'm using the optical drives, I'll often see the errors with them first, and then the whole ATA subsystem seems to go down. Then I get journal commit errors, general read errors, etc, until the system basically locks up. Worst case, it all happens very suddenly, and there's not even anything in the logs. Just a couple messages to the terminal, usually a journal commit error. In my case, the opticall drives are a brand new Pioneer DVD-RW on SATA and an old Plextor on PATA. I mostly see the errors with the latter but have also seen them with the former. I'd thought I'd fixed it by adding pnpacpi=off and pci=nomsi,nommconf to the kernel boot options, as well as libata noacpi=1 to modules.conf, but now I've just had the problem again. I'm now thinking I should try eliminating the Plextor drive. It may be that it's the PATA drive that is causing all the trouble. I'll report if so. FYI, here are the relevant modules being loaded: [root@rghquad rgheck]# lsmod | grep ata pata_amd 20293 0 pata_pdc2027x 17477 0 sata_nv 25157 8 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 IDE interface is an nVidia MCP55, apparently, on an ASUS P5N32-E mb. I doubt very much it's a PS issue in my case. There's not that much in the box. Richard
