We still have a mix of timer and non-timer kernels and I don't see anything like this on any of them.
Are you sure this is 2.4.17? As far as I know, "officially", SLES7 is locked into variations of 2.4.7. The latest kernel upgrades from SuSe are: k_timer-2.4.7-9 k_deflt-2.4.7-44 both dated 5/21/02. > -----Original Message----- > From: John Campbell [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, August 13, 2002 8:53 AM > To: [EMAIL PROTECTED] > Subject: Re: [LINUX-390] ksoftirqd_CPU0 takes 100% > > > >>>>>>>> > > > # top > > > 2:00pm up 5:15, 2 users, load average: 1.00, 1.00, 1.00 > 41 processes: 35 sleeping, 3 running, 3 zombie, 0 stopped > CPU states: 0.3% user, 99.4% system, 0.0% nice, 0.1% idle > Mem: 501980K av, 494408K used, 7572K free, 0K > shrd, 136120K > buff > Swap: 1464376K av, 0K used, 1464376K free > 56796K > cached > > PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME > COMMAND > 4 root 20 19 0 0 0 > RWN > 98.6 0.0 300:11 ksoftirqd_CPU0 > > > # uptime > 2:05pm up 5:20, 2 users, load average: 1.03, 1.03, 1.00 > > > What does it mean? > > btw: SLES7 64bit on LPAR with 2.4.17-timer kernel. > > WBR, Sergey > <<<<<<<< > > Could this be due to the lack of the 100Hz timer pop? > > With a truly "idle" Linux instance you're measuring utilization > from *inside* a rubberized room- this is kind of a "software" > example of the Lorentz-Fitzgerald contraction- your ruler is > changing it's length as the virtuality takes effect.
