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.
