Description ralph 1999-07-22 20:23:40 UTC

Hello,
  Im having a small problem with my new notebook, it locks
up a majority of the time at startup with an 'unable to
mount root fs' error message.  This happens most of the
time unfortunatly, and i have to turn off and on the
notebook as many as 10 times sometime before it works...
(for an unknown reason)  I have a Sony Z-505SX notebook and
other than the sound card not being supported yet,
everything else seems to work fine with it...  Im running
redhat 6.0, i did a dmesg and a few other dumps and
attached them to this bug report, i hope i didnt leave out
any important information :)

Comment 1 ralph 1999-07-22 20:36:59 UTC

oh, it did the same thing on the 2.2.5 kernel (stock redhat) as well
:)

Comment 2 Bill Nottingham 1999-07-22 20:56:59 UTC

What happens if you boot with the 'apm=off' option?
(Unrelated question: is that a real modem, or a WinModem?)

Comment 3 Bill Nottingham 1999-07-22 21:00:59 UTC

Another thing to try is to boot with mem=127M (or some other
lower number.)

Comment 4 greg 1999-07-23 03:30:59 UTC

the apm and the mem option worked :)   yay! thanx :)
i think ill use the mem option (since i use apm)  , where can i put
that in the boot? (/etc/lilo.conf?)

as for the modem, i thing its a Rockwell based pci winmodem :(

here is the bottom of the CAT PCI output (retyped.. im too lazy to
grab a patch cable, my baystack switch is in the other room and im in
bed):
Bus 0, device 11, function 0:
 Communication controller: Unknown vendor Unknown device (rev 1).
  Vendor id=127a. Device id=2005.
  Medium devsel. Fast back-to-back capable. Master Capable.

  Non-prefetchable 32 bit memory at 0xfece0000 [0xfece0000].
  I/O at 0xfca8 [0xfca9].

Comment 5 Bill Nottingham 1999-07-23 15:53:59 UTC

You'd put something in your lilo.conf like:
append="mem=127M"

Unfortunately, it does look like all of the Rockwell PCI modems
are WinModems. :(
