2.4 kernel tweaking
Hi,
I just got a new laptop (a powerpc) running a recent 2.4 kernel
(2.4.20-pre9-ben0) and see a lot of HD access when I do nothing.
I have stopped everything possible and then have:
~$ ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.2 1480 600 ? S 20:42 0:04 init
root 2 0.0 0.0 0 0 ? SW 20:42 0:00 [keventd]
root 3 0.0 0.0 0 0 ? SWN 20:42 0:00 [ksoftirqd_CPU0]
root 4 0.0 0.0 0 0 ? SW 20:42 0:02 [kswapd]
root 5 0.0 0.0 0 0 ? SW 20:42 0:00 [bdflush]
root 6 0.0 0.0 0 0 ? SW 20:42 0:00 [kupdated]
root 12 0.0 0.0 0 0 ? SW 20:42 0:00 [khubd]
root 16 0.0 0.0 0 0 ? SW 20:42 0:00 [kjournald]
root 327 0.0 0.2 1472 588 tty1 S 20:42 0:00 /sbin/getty 38400 tty1
root 328 0.0 0.7 3572 1964 tty2 S 20:42 0:00 -bash
root 329 0.0 0.2 1472 580 tty3 S 20:42 0:00 /sbin/getty 38400 tty3
root 330 0.0 0.2 1472 580 tty4 S 20:42 0:00 /sbin/getty 38400 tty4
root 331 0.0 0.2 1472 580 tty5 S 20:42 0:00 /sbin/getty 38400 tty5
root 332 0.0 0.2 1472 580 tty6 S 20:42 0:00 /sbin/getty 38400 tty6
root 1605 0.0 0.7 4080 1808 tty2 R 23:09 0:00 ps aux
And I still see (and hear) HD access every 20 seconds or so.
I guess it's bdflush or kjournald that does that. Is there a way to
change this?
kjournald is there because of ext3. Could it be responsible for that?
