NetBSD quinn 2.0 NetBSD 2.0 (QUINN-07805) #0: Sat Mar 26 03:45:27 EST 2005  root@quinn:/usr/src/sys/arch/i386/compile/QUINN2 i386
>Description:
I have a tekram scsi controller (trm0).  In 1.6 I had no problems w/ it,
In 2.0 its fine on the 1st boot after power-cycle, but after a reboot, I get:
 trm0: parity error
 sd1(trm0:0:0:1:0) generic HBA error.

whenever I try to access, sd1, and device not configured to disklabel /dev/sd1 , etc.
If I boot into 1.6, it works fine, but boot back into 2.0 and the problem comes back, unless I power-cycle (or halt -p)  -- reset-button is not enough.   The drive is configured to /not/ spin up initially, if that matters.   sd0 is a atapi-zip
sd1 is  ultra-star 18 <IBM, DXHS, 0430>.  Also the cpu is a  VIA C3 Ezra
