I have been attempting to test 2.6.25-rc1 on my Sun Ultra 40 (two

dual-core Opteron 2222 CPUs).


There is some issue with the HPET clocksource which causes it to hang

the boot process if enabled, which I will look into in due course (the

HPET works fine on at least 2.6.19).


More pressing is that the system will not boot at all even with HPET

disabled - kernel gets no further than "NET: Registered protocol family

2".


I cannot think of a way to find out what the problem is, because the

system has only USB ports, and the USB keyboard is not working at this

stage, either because the system has locked up hard, or because the USB

support has not yet loaded (I tried both standard USB-HID and boot

protocol keyboard support, both compiled in). Thus I cannot use

magic-sysrq, or even scrollback to look at boot messages. There is also

no serial port to assist with the latter...


Any thoughts on a procedure for debugging this would be much

appreciated.

I can confirm neither the boot hang with HPET enabled nor the other

unexplained boot hang after "NET: Registered protocol family 2" occur on

2.6.24.2 on the same hardware. I still don't have an appropriate way to

debug the issue on 2.6.25-rc1, though...

Is there any new info on this ? Does the problem still exist with 25-rc7 ?


Thanks,
