ASUS A7V, 1 GHz Athlon, 256 MB, IC35L040AVER07-0 on Promise ATA 100 Controller
System: FreeBSD qualle.private.net 4.5-STABLE FreeBSD 4.5-STABLE #13: Mon Mar 25 22:16:24 CET 2002 root@qualle.private.net:/usr/src/sys/compile/QUALLE i386
The machine panics with a vm_fault when portupgrade is backing up old data. The error is reproducible.
