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 :) -Ralph Bonnell (www.ralph.cx) ###Bad Boot: Linux version 2.3.11 (root@sony.z.aubbs.cx) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #2 Thu Jul 22 12:27:31 EDT 1999 INITIALIZING CPU#0 Detected 364739803 Hz processor.

oh, it did the same thing on the 2.2.5 kernel (stock redhat) as well :)
What happens if you boot with the 'apm=off' option? (Unrelated question: is that a real modem, or a WinModem?)
Another thing to try is to boot with mem=127M (or some other lower number.)
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).

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. :(
