[as nearly seen on tech-x11]
Now, with kernel, userland and X all built from yesterday's source, on
a Toshiba Satellite S1800-700

- machine hangs on boot if agp is enabled in the kernel config (just after
  printing its message),

- xf86cfg gets

  PID USERNAME PRI NICE   SIZE   RES STATE      TIME   WCPU    CPU COMMAND
  224 root      57    0  6884K 6160K RUN      141:50 99.02% 99.02% XFree86

  and all one sees is the cursor in the top left hand corner..

When the laptop hangs with agp defined, and DDB enabled, ctl+alt+esc doesn't
drop me into ddb.

The XFree86 -configure process is

#0  0x085cdbaf in ?? ()
#1  0x085f516a in ?? ()
#2  0x0860612f in ?? ()
#3  0x085fba69 in ?? ()

#10 0x0806ca53 in InitOutput ()
#11 0x080b5d7d in main ()
#12 0x0806b7c2 in ___start ()

here, but it'll take a while to build with symbols..

Any idea where to look?

Cheers,
