Message-ID: <013c01c2383c$8b2d4bf0$638317d2@pacific.net.au> (raw)
In Linux 2.4.19ac3rc3 on IBM x330/x340 SMP systems we're seeing this:

Note the time skew in the "ps" output (the clock time is correct).
This is happening on all ten IBM x330/x340's we're running this in SMP
on this kernel.
We have fourteen Intel ISP 2150 servers running UP with IO-APIC on SMP
motherboards which are not experiencing this issue.
