Hi all, I upgraded my ancient ThinkPad 380D from some 5.2-CURRENT to yesterdays 6.0-CURRENT. Booting GENERIC I get: Mounting root from ufs:/dev/ad0s2a g_vfs_done():ad0s2a[WRITE(offset=65536, length=8192)]error = 1 panic: bundirty: buffer 0xc290a170 still on queue 1 With a custom kernel (no INVARIANTS or WITNESS) I still get the g_vfs_done() message, but no panic, and the machine seems to run normally. I see somebody else was asking about the same message here yesterday: http://lists.freebsd.org/pipermail/freebsd-current/2004-November/043012.html Any ideas? Full dmesg and traceback from DDB below. Unfortunately I haven't been able to get remote debugging working on this machine (it hangs at the boot: prompt with -d in /boot.config) so I don't know what further debugging I can do...
