Seems that there is a pattern:
The most problems I see with SuSE are realted to VIA Chpsets and NVIdia Cards :-(((
Check your /var/log/messages
Boot your system with following options:
pci=noapic acpi=off noapic
(You for sure know, acpi and apic are different things)
You can pass those options in the boot menu screen.
If this does not help:
1) If 3D for your grafic card is on, then *DISABLE* it.
2) Try to disable DMA for you drives.
