FPU emulation problems in 2.4

Hello everyone,

In my quest to get 2.4 and netfilter running on my machines
I have been having tons of problems on some [34]86sx machines that we use. On all of them the kernel freezes hard right after saying

VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 196k freed

No keyboard, no SysRq, need a hard reset. I also tried this on an AMD K6-2. With hardware FPU it works fine, but loading with no387 gives an error:

FPU Emulator: Unknown prefix byte 0x00, probably due to FPU Emulator: self-modifying code! (emulation impossible) FPU Emulator: Internet error type 0x0126
At 00000023:0286

	SW: b=1  st=0  es=1  sf=1  cc=0010 ef=111111
	CW: ic=0 rc=00 pc=11 iem=0         ef=111111

Searching the archives showed a bug report against 2.1.5 that said basically the same thing. Unfortunately there were no more messages in the thread.
