Just compiled my 2.1.76 kernel once  again this time using egcs-971225
to see if the `-funroll-all-loops' still persists.

IT'S FIXED!

I writing this e-mail  on the freshly compiled  kernel and didn't  had
any problems so far.  I'll only have  to reboot later  on to sent this
mail out into  the world, as  ISDN is still broken  in the most recent
kernels :-(

Keep up the good work, cheers 1998
