>Description:

I have a PIII/500 with an Advansys 3940 scsi controller.  This machine has
been happily running 1.4K as a production webserver with 200+ day uptimes. I
tried to upgrade to 1.5 and subsequently -current, by booting a kernel and
then untarring base.tgz over top of my 1.4K binaries.  Here's what happens:


	grok# foreach I (*.tgz)
	? gzcat $I | (cd / ; tar xpf - )
	? end
	adw0: DMA Error. Reseting bus
	^@^C^C^C^C^Cadw0: DMA Error. Reseting bus
	^C^C^C^C

	adw0: DMA Error. Reseting bus:37:04 grok /netbsd: adw0: DMA Error. Reseting bus
	 
	adw0: DMA Error. Reseting bus

....at which point my filesystem is hosed.

Here's a dmesg:
