Is this with libata (and ata_piix in particular)? Try the following experiment: Switch to single user mode and remount the partitions read only. Perform the following commands: # cat some-big-file > /dev/null & # echo 1 > /sys/block/sda/queue/protect Repeat the second one several times while the read operation of the first one is in progress. Make sure that you actually hear the drive park heads and resume normal operation. My system freezes after the third park command at the latest. Mind you, this doesn't apply to the old style IDE drivers. Regards, Elias -- The linux-thinkpad mailing list home page is at: http://mailman.linux-thinkpad.org/mailman/listinfo/linux-thinkpad
