Kernel Panic on PowerMac G4 "Digital Audio" during boot

[Alexander Coers]

Hi all,

I wanted to try (after a long time) FreeBSD on my PowerMac. I used the 11.1 installation CD. Installation went smooth, everything worked well.
If I now boot FreeBSD (currently selecting in OF boot manager with left Alt) from SSD, the kernel needs ages (up to 2 min) to load (time between message from loader and autoboot prompt).
Shortly after that the kernel panics right after initialisation of gme0 and cryptosoft0 with
panic: timed sleep before timers are working
cpuid = 0
KDB: stack backtrace:
00 0x4c6f00. at vpanic+0x1d4
01 0x4c6f9c at panic+0x54
02 0x534988 at sleepq_set_timeout_sbt+0x78
03 0x4d3c4c at _sleep+0x28c
04 0x821af0 at swapper+0x374
05 0x4484fc at si_startup+0x238

I am a little bit puzzled since the CD boots with the same kernel without issues. The box features a 1.6 GHz NewerTek CPU upgrade with 1.5 GB RAM.

Any ideas?

Regards,
 Alexander
