A friend of a friend is having problems with a machine he recently updated from 2.2.7 -> 2.2-stable. Basically it seems the clock is all messed up, and weird things are being shown for process time and cpu useage: doing a ps -aux USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND bright 1799 0.0 0.6 672 796 p1 R+ 31Dec69 0:00.00 -bash (bash) root 1 0.0 0.2 412 248 ?? Is 2:11AM 0:00.02 /sbin/init -- root 2 0.0 0.0 0 12 ?? DL 2:11AM 0:00.00 (pagedaemon) ... -brokenbox::bright:~$ uptime uptime: /dev//3: No such file or directory uptime: /dev//²½n6ttyp4: No such file or directory 11:35AM up 1:24, 2 users, load averages: 0.21, 0.15, 0.10 (yes i know utmp/wtmp are broken, i had him recompile screen/sshd) -brokenbox::bright:~$ date Wed Dec 9 11:36:20 PST 1998 top: CPU states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 0.0% idle PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 486 spice 2 0 1536K 2220K select 0:11 0.00% 0.00% eggdrop-1.3.20 311 myneid 2 0 1072K 1576K select 0:11 0.00% 0.00% irc-EPIC4pre1. top can not get WCPU/CPU times.. :/ If you haven't noticed: the time on bash is way off, in fact it seems pre-epoch i think. Other processes are showing start times that are earlier than when the machine was booted. He also says that machine is acting kinda funny, meaning the scheduling is bursty, but i'm unsure about that. i've double checked perms on: /dev/drum, /dev/kmem, /dev/mem and procfs they seem normal, the devs are rw-r------ root, kmem the kernel_kvm.db file looks fine. we've rm -rf /usr/obj /usr/src and recvsup and re-made world but it hasn't helped. ktracing top doesn't show it getting errors opening anything... btw, apm is off in the kernel and i'm seeing nothing odd in /var/log/messages and nothing odd in dmesg output. I haven't really been tracking -stable and i'm really stumped, any suggestions? anyone else seeing problems like this with a recent cvsup? thanks, and please cc: me as i'm not subscribed to this list.
