Hi,
This week I upgraded the OpenBSD install on my laptop to 5.0-current, and I
noticed some applications running very sluggish. Running 'top' showed me
that CPU0 has an interrupt load of 80-90%:
45 processes: 44 idle, 1 on processor
CPU0 states: 2.6% user, 0.0% nice, 3.8% system, 89.0% interrupt, 4.6%
idle
CPU1 states: 17.8% user, 0.0% nice, 28.0% system, 0.0% interrupt, 54.2%
idle
Memory: Real: 638M/1025M act/tot Free: 945M Cache: 282M Swap: 0K/2293M
The laptop is a Samsung N210. Any idea what might be the problem, or how I
might gather some more information?
Thanks in advance,
-Leroy
