Tom,

Thanks for the hint on softdeps, but I'm not that functionality. In fact, I'm
still with the Generic kernel (would recompiling be of any use right now?)

Perhaps the debugging functionality for IDE devices would, but in the
logs (or on screen) I see no real drive errors or hickups. All that happens
are filesystem panics. It also seems to happen only at higher (although
5Mb/s is not what I'd call a record speed) transfer speeds.

Given the text on the VIA chipsets in the port-i386 list, it may be wise
to add that the discs in my system are in the following layout:
	Primary IDE controller
		master:	wd0	(Quantum Fireball 3.2G)
		slave:	wd1	(WD 4.1G)
	Secondary IDE controller
		master:	wd2	(IBM Deskstar 40G)

On my old (Award 4.51PG) BIOS, the drive is only reported to have
an 8.2G size, but NetBSD definitely sees the entire thing while reading
the dmesg output.

Running at lower speeds (with IDE block mode disabled) the problem
doesn't occur. Only, the system loses just about every last bit of disc
performance.

Is there anyone with a clue. Since running under Linux for the last two
years gave no problems at all. Yet, I'd rather to run NetBSD on it.

Thanks in advance,

Rogier Krieger
