I assume Linux boot floppy stops at the same point?

I can't reproduce this error. Using latest CVS, 'qemu -m 350' works perfectly
fine for me. In fact it works fine for qemu 0.5.5 as well.
Only difference is that I use kerenl 2.4.26 and I have the rtc set to 100hz
instead of 1024hz. I also have never installed or used kqemu.

Can you run gdb on it and figure out where in the code it freezes?
