OpenBSD 4.2 i386 -snapshot- hangs at boot an Dell Poweredge2650

[Falk Brockerhoff]

Hello,

I just installied OpenBSD 4.2 i386 Release on a Dell Poweredge 2650. 
Install works fine, but the server hangs at boot. "enable acpi" on the 
UKC fixed this.

After succesfully booting I updated to the latest snapshot (the laste 
before the actual from 15.01.2008) with the help of 
OpenBSD-binary-upgrade. After updating the machine won't boot any more - 
neither with or without acpi enabled.

Does anyone else had such a problem and can give me a hint? Or can you 
point me a way to provide helpful information (additional to the last 
seen lines on the monitor - I will provide them when I'm in front of the 
server next time)?

Regards,

Falk
