Things should be a little more stable... The CONFIG_PREEMPT+SMP problem I was having went away when gcc-2.95.3 was used in place of 2.91.66. Which is a bit of a problem because _someone_ has to keep an eye on 2.91.66 compatibility as long as it continues to be required for sparc builds. There is a memory corruption problem happening deep in the scsi code when the hot-n-cold pages patch is present. Current theory is that this is a use-after-free problem in scsi, and that the hot-n-cold pages patch is exposing it because its LIFO page queue will hand out a page immediately after this cpu freed it. The workaround is a patch -R of page-reservation.patch pagevec-hot-cold-hint.patch readahead-cold-pages.patch hot_cold_pages.patch in that order.
