 Daniel,
 
   Oops I didn't mean for you to do an entire 4.3 install! :-)  Note section
 2.1.6 of the FreeBSD 4.4 Release notes regarding the
 new PCI interrupt path routing.  Looks like your system is one of the
 ones that this doesen't work for.
 
   If you would, see if there's a BIOS update for your laptop from it's
 manufacturer and apply that, then boot it from a 4.4 RELEASE floppy and
 see if it panics again.  Let us know the results of this.
 
   If that doesen't work then try the workaround:
 
     ok set hw.pcic.intr_path="1"
     ok set hw.pcic.irq="0"
 
   that is listed in the release notes on the 4.4 boot floppy and let us know
 if that works.  If it does then just wait for version 4.5 to come out and you
 can probably use the workaround on that.
 
   Please supply us with the exact manufacturer and model# of laptop
 plus any BIOS version so we can put that in the known problems area at
 the end of the INSTALL.TXT
 
   If the pcic isa interrupt hack works then this PR probably needs to be
 looked at by Warner Losh.
 
 
 Ted Mittelstaedt
