I have tried to boot many different Linux boot CD images with QEMU under 
FreeBSD 6-stable. With all the boot CD images I have tried, I always see 
a lot of "hdb: DSC timeout" messages and it takes forever to boot (~45 
minutes). The CPU usage is very low most of the time, and the hard drive 
does not seam to work very hard...

I am using the latest qemu + kqemu-kmod ports and did not experience 
that kind of problem with a Win2k guest

Thanks!
