Description Jason M. Sullivan 1999-07-13 16:30:09 EDT
When the Redhat 6.0 Linux kernal boots up on my TravelMate,
it goes though some sort of PCI peer probing thing with
messages of the form (typed from memory)

PCI: found peer at 0x00
PCI: found peer at 0x01

...and this continues up until...

PCI: found peer at 0xff

...needless to say, this takes a while. A good 15min on a
P120 with 24Mb of RAM.  I'm guessing this isn't supposed to
happen (I don't have 255 of anything PCI related in this
laptop).  Is there some sort of boot param. that I can enter
to limit this probing annoyance?
Comment 1 Bill Nottingham 1999-07-13 17:00:59 EDT
Try booting with the 'nopeer' option.
Comment 2 Anonymous 1999-07-14 21:35:59 EDT
That did it.  Thanks!

I read in the BootPrompt documetation (duh, shoulda gone there first)
about the argument, but I don't quite understand the nature of why
the PCI bus freaks out without it.  Oh well.  Thanks again!
