Hi!

I have one NetBSD 1.0 66MHz 486 + aha + SMC Elite + 32 MB ram + 2G disk runn=
ing.

Every night at 3 a clock I am getting this messages to the /var/log/messages=
:

Nov 18 02:37:44 kaarna /netbsd: aha0: DMA beyond end of ISA
Nov 18 02:37:46 kaarna /netbsd: sd0: not queued
Nov 18 02:37:47 kaarna /netbsd: aha0: DMA beyond end of ISA
Nov 18 02:37:47 kaarna /netbsd: sd0: not queuedaha0: DMA beyond end of ISA
Nov 18 02:37:47 kaarna last message repeated 19 times

And same on the console.

The fsck is doing it. It is raporting a lot of errors like (100k bytes of
this text):

168, 169, 170, 171, 172, 173, 174, 175,

At boottime no errors in fsck.

Is there some problem  on the disk or is fsck raporting wrong?
