Boot hangs on ips0: resetting adapter, this may take up to 5 minutes

[Oleg Sharoiko]

Hello!

I'm trying to install 6.0 on IBM eServer xSeries 226 (2 CPUs, IBM 
ServeRAID 6i). During normal boot GENERIC kernel hangs with the last 
message being

ips0: resetting adapter, this may take up to 5 minutes

Ctrl-Alt-Del doesn't work. Pressing power button doesn't work either, 
have to push it and wait for several seconds to switch the system off.

With hint.apic.0.disabled=1 GENERIC seems to boot fine. It's also possible 
to boot FreeBSD/i386 when hyper-threading is enabled (4 logical CPUs) and 
kernel has SMP option (just tried default SMP kernel). With only 2 CPUs 
(HTT disabled) SMP kernel also hangs at the same point. FreeBSD/amd64 only 
boots with apic disabled. This is not specific for 6.0 as RELENG_6 and 
CURRENT also have this problem.

Could somebody please help me debugging this problem? Logs of verbose 
boots are available at http://rsu.ru/~os/ips/ I'm ready to provide any 
possible help needed to resolve this issue. I'd greatly appreciate any 
help.
