Hello,

I'm getting some problems on a 1.4/i386 system (Pentium 166MHz) and maybe
some here can tell me what is going on.


PROBLEM:

While copying a large file (about 17.8MB in size) from a file system 
located on a Seagate disk (disk wd1) to a file system on a Western 
Digital disk (disk wd2) the following error messages appear in the 
window for the xconsole program (X Window System is running):

pciide0:0:1: lost interrupt
        type: ata
        c_bcount: 32768

This occurs on a single user system running NetBSD 1.4, but the problem has
also been observed in the past when the machine was running NetBSD 1.3.3.

The output from dmesg is as follows:

Anyone know why this is happening?? Sometimes the system allows me to
continmue after these messages come out, other times the system is
"frozen" and I can't do anything. When that happens, I have to reboot and
then deal with problems like fsck'ing the file systems.
