DragonFly hangs on laptop

[Sascha Wildner <saw@xxxxxxxxx>]

Hi all,

I'm trying to get DragonFly to run on an aged 400MHz Celeron Laptop 
(Gericom Overdose 2). It hangs somewhere in the clock calibration code.

When I boot from the live CD (GCC2 snapshot from March 23 as well as 
homemade ISOs from today) it sometimes hangs at (from boot -v):

Calibrating clock(s) ...

I haven't checked where exactly it hangs in this case.

Sometimes it will advance a bit further and give me:

Calibrating clock(s) ... TSC clock: 399366840 Hz, i8254 clock: 1193077 Hz
CLK_USE_I8254_CALIBRATION not specified - using default frequency
CLK_USE_TSC_CALIBRATION not specified - using old calibration method

Some printfs I inserted showed that it advances up to the DELAY(1000000) 
in startrtclock() from where it won't return. old_tsc is somewhere in 
between 1400000000 and 1700000000.

I haven't tried CLK_USE_I8254_CALIBRATION or CLK_USE_TSC_CALIBRATION in 
my kernel config yet (don't know if it would help and no more blank CDs 
left :).

Which one of the two scenarios happens seems to be random. FreeBSD 4.10 
and 6 also hang at early stages on this machine. Linux and Windoze come 
up nicely though.

Sascha
