I have two machines for testing: 1) SMP box is dual PIII, SCSI, 1GB, RH 7.3 base distro, X not installed. 2) UP box is PIII, IDE, 256MB, LM 9.0 base distro, X and KDE 3.0.3. The build failure and lockups were on the UP box. The SMP box also ran 2.5.44-mm2 for several hours under load with no failures. It was used to successfully build the UP 2.5.44-mm2 kernel. > > But it should have responded to pings even if deadlocked there Yep, that was weird. I'm only certain about the first hang when it did not respond to pings. . > > Are you using "nmi_watchdog=1"? > Nope. My understanding is that is only applicable for SMP systems, but I can add that to the lilo.conf append line if it would do any good on this troublesome UP box.
