[Bug 35993] Try booting with noapic - Re: hang on an IBM NetVista PC

[Peter Whittaker]

My NetVista M42 had "weird lockup problems" that were due to
timer/interrupt handling issues. I don't have a fix, but I do have a
workaround: Boot with the noapic kernel option (no other options
necessary).

Try that on your machine and let us know if it changes anything (that
is, set the noapic option, but do not set others, don't set nolapic or
acpi=off).

The following bugs appear to be related:

#35274, NetVista 6824 becomes unresponsive after some time, OK after
reboot: Exactly the same symptons I had, also same as #71023.

#35993, hang on an IBM NetVista PC: Similar symptons. Some have resolved
with BIOS update; no such luck for me, I have latest BIOS. Others have
use noapic nolapic, but nolapic unnecessary for me.

#69526, intel 845G using i810 driver freezes xorg: Similar behavior,
esp. comparable to #35993, may be timer/interrupt issue and not related
to the 845G at all.

#71023, Sparodically slow system clock: I am tempted to mark this one a
duplicate of 35274.

FWIW, YMMV.
