Subject: pre6 oddity

Hi Marcelo,

On two of my machines running pre6, I am seeing top report very odd
priorities for two kernel tasks:

PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU
COMMAND

8 root 18446744073709551615 -20 0 0 0 SW< 0.0
0.0 0:00 0 mdrecoveryd
16 root 18446744073709551615 -20 0 0 0 SW< 0.0
0.0 0:00 0 raid1d


Something related to the scheduling changes going on ?

(RedHat 9 base system)

Hi Marcelo,

This was a procps bug. 2.0.11 I believe. There was something like a
printf("%ull", prio) with prio=-1, which prints 2^64-1 (the high number seen
here). Upgrading to 2.0.13 fixed the problem for me.

Cheers,
Willy

Confirmed - I updated to procps 3.1.11 and the oddity with the display
is gone.

Thanks Willy.
