Comment 75 for bug 607560

Hello all.

Wanted to inform that there's fresh thread in Archlinux forums and associated bug on bugzilla.kernel.org with some debugging instructions:
https://bbs.archlinux.org/viewtopic.php?id=139087 - Intense disk IO (jbd2 and flush) blocks user interface
https://bugzilla.kernel.org/show_bug.cgi?id=42895 - jbd2 makes all system unresponsive

Even if it's not exactly the same bug, still there's someone with jbd2 writing every ~3 secs and he's got his problem solved (or at least now he knows that in his case it was Chrome's activity).

I myself wasn't so lucky. I hear HDD activity but don't see anything extraordinary in ftrace output:

Bug report is still open! If you have something to say or ask - it seems to be good time to do it.
