It is really weird. I built gnumach with --disable-device-drivers
--enable-ide --enable-kdb.
I boot hurd with the new kernel and run the user-level network drivers
but got a kernel
general protection trap. I tried several drivers and always got the
same problem.
The error can be seen at http://i.imagehost.org/0382/Screenshot.png.

addr2line shows me 0x1076e6 is at
/root/gnumach-build/../gnumach/i386/i386/spl.S:217
I don't know whether the error is caused by my change in gnumach or
the error exists in
gnumach itself. It's probably not very easy to check as the error
occurs when a user-level
driver runs.
