After 5 and half hour of compilation ;) I have some results:
- command sysctl vm.block_dump=1 (so I can see writes and reads with dmesg |
grep -e READ -e WRITE) makes syslog-ng to write every few seconds which
triggers jbd2 as well. So I fell in my own trap. Killing syslog helps there.
- console-kit-daemon also triggers jbd2. I'm not sure why but it writes over
and over again in text-mode. Killing it helps until you log in within another
console, then it starts again. It quiets in X mode, though. Strange.
- Killing console-kit-daemon in text-mode enables possibility to spin-down the
disk for a minute or two. Then some pdflush or cron job starts.
So it seems there is nothing wrong with ext4. Anyway, thanks for the patch, it
was very helpful to determine what is wrong and solve people's problems.
