Hello All, I used the appended patch which enables the assert() in the FPU emulator. The result (running in qemu) is: [snip] Will now check root file system:fsck 1.40-WIP (14-Nov-2006) [/sbin/fsck.ext3 (1) -- /] fsck.ext3 -a -C0 /dev/hda1 /dev/hda1: clean, 21846/131072 files, 371295/524272 blocks .

I don't know i f this just means one of the asserts is broken or if there is something wrong with the FPU emulation.
