I am not sure if it has been reported already but this commit

http://git.qemu.org/?p=qemu.git;a=commitdiff;h=d7a51dbbaa70677846453f8c961590913052dd86

(replacing pc-bios/bios.bin with a newer version)
breaks booting of FreeBSD on recent qemu (starting roughly with qemu-1.3.0-rc2).

Using a FreeBSD host, and a FreeBSD guest,
the qemu thread runs at 100% and the console is stuck
after the 'pci0' probe:

                           
...
hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0        
Timecounter "HPET" frequency 100000000 Hz quality 950                           
Timecounter "ACPI-fast" frequency 3579545 Hz quality 900                        
acpi_timer0: <24-bit timer at 3.579545MHz> port 0xb008-0xb00b on acpi0          
pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0                         
pci0: <ACPI PCI bus> on pcib0

Reverting the bios fixes things.
I wonder if it isn't the case of reverting this change ?

cheers
