Dear NetBSD/alpha:

Today I upgraded manually from 1.5.1 to 1.5.2 by booting from a CD I made
and then following these steps

# mount /dev/sd0a /mnt
# mount /dev/sd0d /mnt/usr
# mount /dev/cd0a /mnt2
# cd /mnt
# pax -zrpe -f /mnt2/alpha/binary/sets/base.tgz

etc., etc. for the other tgz files.

When pax was running many lines like this were printed on the console

cd0(asc0:4:0): soft error (corrected), info = 219232 (decimal), data = 00
00 000
cd0(asc0:4:0): soft error (corrected), info = 223908 (decimal), data = 00
00 000
cd0(asc0:4:0): soft error (corrected), info = 224044 (decimal), data = 00
00 000

I suppose these errors were produced by a hardware problem in my CD-ROM
drive?  I used the same CD to install from scratch on another machine
without any such messages.

Could you tell me which part of the system detected and corrected the
errors and printed the error messages--would that be the kernel?  What do
the info and data numbers mean?

Here's some info about the machine, which is a 3000/400, from SRM:
