This has happened somewhat rarely on a variety of Fedora kernel versions. Basically, sometimes IO will get really slow and I'll start getting "ata1: command 0x35 timeout, stat 0x50 host_stat 0x4" in my logs, with the occasional "ata1: command 0x25 timeout, stat 0x50 host_stat 0x4" and "ata1: command 0xb0 timeout, stat 0x50 host_stat 0x0" thrown in for good measure. The disk (and/or controller) isn't unresponsive -- I can do a smartctl -a -d ata /dev/sda and it'll complete (eventually), and IO to the disk continues (very slowly), but it's generally unusable until the next reboot. Any help would be appreciated. Thanks, Nicholas. -- Nicholas Miell
