With the latest commits, I've noticed that the system tends to
"halt" temporarily when there is a lot of disk activity. For example,
doing cp with a lot of really big files caused XFree86 to freeze while the
file transfer was taking place. The file transer was not affected in
any way during the "freeze". It seems like the multi-tasking is
affected with heavy disk activity. I've got softupdates enabled, if that
helps.
This problem just cropped up about 2 days ago or sooner. I've attached my
dmesg. I've never seen this problem before. Maybe there was a change
made to the scheduler and/or ata driver?
