comment Can I block log messages from specific devices or drivers?
@msw Thanks, a driver update did the trick. Still interested in the question, as this is not the first time (and probably not the last) I have had "log spamming", and I'd like to know a general solution.

I don't have a system to try it out on at the moment, but yeah - it sounds like it should work :) Thanks!

comment Is a disk/ata timeout exception dangerous?
For future readers with similar issues: This may or may not be related to the bug SATA link power management causes disk errors. The error details differ, but I did use SATA link power management.

comment Is the “magic” 200 lines kernel patch included?
@psusi Agree that most users probably won't notice a difference. (Although the grouping is apparently no longer terminal-based.) Whether I will remains to be seen :) (I'm running Boinc and F@H, attempting to maximize CPU usage and desktop responsiveness simultaneously.)

comment Is the “magic” 200 lines kernel patch included?
@psusi I assume it also helps if you are running distributed computing projects (Boinc, SETI, Folding@home ...), if you are a doing hour-long background compiles, probably a handful of other use cases as well. Although a majority of users may never e.g. compile kernels or run Boinc, I wouldn't go so far as to call those that do so insane :)

Just thinking aloud here: 100% IOWait could mean that the file system is waiting for the disk to wake from a low power state - agressive power saving is a major feature of the WD Greens. But not sure why it would lock the system. There's presumably a /dev/sda as well - which disk holds what? Like "root on sda, home on sdb"?

I can tell you what they are: They are part of the file system - flush writes the RAM buffer/cache to disk, and jbd2 deals with the ext4 journal.
