Comment 1 Dmitri A. Sergatskov 2003-02-26 20:20:20 UTC

I guess this is a "Me too" comment. The problem is pretty much the same, though
the hardware is quite different:

Tyan Tiger MP S2460 2xAMD MP 2400+
CD/RW is on Maxtor (promise OEM 133TX2) 133 controller (hdg)
I have to boot with 'noapic' or computer locks-up sporadically.

Comment 2 Dmitri A. Sergatskov 2003-02-27 18:54:04 UTC

Upgrading to the rawhide kernel (2.4.20-2.54smp) seems to solve both problems:
I can read CDs again and it has not locked up (there is no 'noapic' this time)
yet (~20 hours).

Sincerely,

Dmitri.
