Created attachment 20441 [details] dmesg output
Please reopen this bug; it is still present in 2.6.29-rc7. My system is a Dell 630 laptop (Core2 duo). A kernel arg of 'acpi=off' causes the bug to not occur, but that also limits to the system to using just one CPU core. dmesg output is attached. Error reported in syslog is (this error is repeated many times): Mar 5 11:45:56 jskusb kernel: [ 319.568193] ata1.00: qc timeout (cmd 0xa0) Mar 5 11:45:56 jskusb kernel: [ 319.568216] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Mar 5 11:45:56 jskusb kernel: [ 319.568231] ata1.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Mar 5 11:45:56 jskusb kernel: [ 319.568233] cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Mar 5 11:45:56 jskusb kernel: [ 319.568235] res 51/20:03:00:00:00/00:00:00:00:00/a0 Emask 0x5 (timeout) Mar 5 11:45:56 jskusb kernel: [ 319.568242] ata1.00: status: { DRDY ERR } Mar 5 11:46:01 jskusb kernel: [ 324.612172] ata1: link is slow to respond, please be patient (ready=0) Mar 5 11:46:06 jskusb kernel: [ 329.596160] ata1: device not ready (errno=-16), forcing hardreset Mar 5 11:46:06 jskusb kernel: [ 329.596177] ata1: soft resetting link Mar 5 11:46:06 jskusb kernel: [ 329.776652] ata1.00: configured for UDMA/33 Mar 5 11:46:06 jskusb kernel: [ 329.780908] ata1: EH complete
