i386 with ACPI enabled kernel
>Description:
NetBSD 2.0_RC2 and NetBSD 2.0_RC3 with UP i386 ACPI enabled kernel failed to reboot. I downloaded NetBSD 2.0_RC1 from FTP and installed to HP/Compaq NX9010 (Intel processor, VIA chipset) laptop. After that, I downloaded RC2 source and compiled a new kernel with ACPI support. A few days later, updated source from CVS, compiled new kernel, and wanted to "reboot". Laptop couldn't reboot. 

Syncing disks... done
Rebooting...

At this point, system freezes.

After shutting down from power switch, rebooted my laptop with new kernel (RC3) and a few hours later "halt"ed. 

Safe to power off
       or
Press any key to reboot

(Mesage above may be a little different from actual message)
I pressed a key,

Rebooting...

message appeared on my screen and system couldn't reboot, just frozen.
Today, i want to "poweroff", and saw

Syncing disks... done
kernel: page fault trap, code 0
Stopped at   netbsd:sip_rxintr+3d3: mol %edx,0x20(%esi)

message. I wrote down
db> reboot

and system hanged.
>How-To-Repeat:
halt and reboot commands causes system hangs. (Not every time but, some times) poweroff command fails.
