Hi,

I´m running NetBSD-5.1 but with the netbsd-GENERIC.MP kernel from
netbsd-daily (NetBSD-daily/netbsd-5/201106181530Z).
When I have the system up and running, CPU1 is always 100% busy with
¨interrupt¨ according to the top utility. CPU0 shows more normal
results in top with about 100% idle. Is there another kernel I should try?
like -current?

The system has two ROSS hypersparc:
from dmesg:

mainbus0 (root): SUNW,SPARCstation-20: hostid 7277a997
cpu0 at mainbus0: mid 8: RT620/625 @ 150 MHz, on-chip FPU
cpu0: 512K byte write-back, 32 bytes/line, sw flush: cache enabled
cpu1 at mainbus0: mid 10: RT620/625 @ 150 MHz, on-chip FPU
cpu1: 512K byte write-back, 32 bytes/line, sw flush: cache enabled
