System: GigaByte 586-DX, 2xP5-133, 48MB, on-board 7880 SCSI,
4GB IBM DCAS-34330W.
Current as of CTM src-cur 3477 (< 48 hours).
Softupdates enabled on _all_ filesystems: no problem, did
two make buildworlds/installworld in a row, as long
as AHC_TAGENABLE is off.
If I enable AHC_TAGENABLE, and push the system a bit (lots
of FS activity) -> freeze. Last time it happened was with X,
so I'd have to do it again in text mode to write down the AHC
TAG messages...
Config file follows.
