Hi,

As of kernel 2.4.5 I'm getting two symptoms:

| bash$ w
| 11:27:35 up 1 day, 21:24, 16 users, load average: 0.06, 0.04, 0.00
| USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
| bash$
(note lack of actual data)

and in top:

| 11:42:22 up 1 day, 21:39, 12 users, load average: 0.08, 0.04, 0.01
| 0 processes: 0 sleeping, 0 running, 0 zombie, 0 stopped
| CPU states: 0.2% user, 0.4% system, 0.0% nice, 99.4% idle
| Mem: 188756K total, 175548K used, 13208K free, 26508K buffers
| Swap: 257000K total, 19020K used, 237980K free, 98708K cached
|
| PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
|
|
|
|

(tends to 100.0% idle over time - refresh interval of 3s.)

In either case, this sits around for about 10s and then normal service is
resumed. During outages, the rest of the box behaves as normal.

I was informed this is due to a `locking issue' that only ReiserFS stumbled
upon (the above happened most times when I write to /home or /var/log, both
of which are ReiserFS), and that it was fixed in 2.4.6 (pre3). I'm now
running 2.4.7-pre3 and it *still* occurs, although not as frequently as
before (was roughly 2 out of every 3 writes to a reiser partition; now less
than predictable).

Data: Debian/Testing updated daily. Filesystems used:

/dev/hda1 on / type xfs (rw)
/dev/hda4 on /var/spool type xfs (rw,noexec,nosuid,nodev)
/dev/hda5 on /var type reiserfs (rw,nosuid,nodev,noatime)
/dev/hda7 on /usr/local type reiserfs (rw)
/dev/hda8 on /home type reiserfs (rw,nosuid,nodev,noatime)

If anyone else has experienced this and/or has clues what's going wrong,
I'd be grateful.

TIA,

~Tim
