I see you already fixed it. Works fine now. Thanks a lot.

Well, at least for a 32-bit kernel. If I compile a 64-bit
kernel it still stops when it should start init. Any ideas?

Is this really related to my TLB exception handler patch? The 64bit
versions of it are pretty well tested now, so it would be most likely
some flaw specific to your CPU. The 64bit kernel had no optimized TLB
handlers before.

Don't know. It's just that it worked before. But I might just
have been lucky then. I just checked again and found that without
SMP enabled 64 bit is working too. So the problem might indeed
not be related to your patch.
Thanks for your help anyway.
