Can you recompile a kernel with 'options DIAGNOSTIC' ?
My alpha didn't survive more than a few minutes after I updated it to 1.6,
it died with:
panic: kernel diagnostic assertion "startoff < endoff || endoff == 0" failed: file "/home/src/sys/arch/alpha/compile/DISCO/../../../../miscfs/genfs/genfs_vnops.c", line 1041

I hope I'll get a core dump.
