This past month or so, my Lenovo T440s laptop has started doing strange
2-second pauses at random intervals, sometimes a few times per minute.
How would you look for the source of this trouble? There's nothing in /var/log
showing when it happens. No log entries added there. Where else would you
look?
The easiest way to spot it in action is with a simple ls :
cd /tmp
mkdir a b c
time ls a
0m00.00s real 0m00.00s user 0m00.01s system
time ls b
0m03.22s real 0m00.00s user 0m00.01s system # there is the random
pause
time ls c
0m00.00s real 0m00.00s user 0m00.00s system
time ls b
0m00.00s real 0m00.00s user 0m00.00s system
I've tried it running OpenBSD 6.3 RELEASE, STABLE, and CURRENT. Happens with
all.
I wiped the entire drive (dd if=/dev/zero) then re-installed from scratch, and
it still happens.
It happens whether running X or just in the initial raw console without startx.
I know it isn't an OpenBSD problem, but any suggestions where you'd look if it
was you?
Thank you.
