NoName Alpha, trident ISA VGA card. My x86 PC does not exhibit this problem.
>Description:
When generating large chunks of console output on a graphics console on
my Alpha bits and pieces of it end up in /var/log/messages. Here's what I
see:

Jan 27 01:03:40 slugout /kernel: 0 b681 4826 0005 f420 f000 203f 9681 4821
Jan 27 01:04:05 slugout /kernel: 5f74 6564 6376 616c 7373
Jan 27 01:04:35 slugout /kernel: 0 bf20 0036 fc00 ffff 0104 0000 0000 0000
Jan 27 01:04:40 slugout /kernel: 0 23e0 0046 fc00 ffff 0000 0000 0000 0000
Jan 27 01:04:40 slugout /kernel: b0e118>0258590 0018 0000 0000 0000 2b5e 0001 00 0007

Message from syslogd@slugout at Sat Jan 27 01:04:40 2001 ...
slugout /kernel: b0e118>0258590 0018 0000 0000 0000 2b5e 0001 0001 0007
Jan 27 01:05:00 slugout /kernel: 0 6963 6b5f 756c 6764 5f65 6e75 7469 7300
Jan 27 01:05:05 slugout /kernel: 00 0000 0778 0000 0000 0000
Jan 27 01:05:35 slugout /kernel: 0 0020 a46b 0000 a483 0004 a044 f622 4841
 
Notice that the information has its date stamps intact although the
strings are only parts of the original, they're logged from /kernel and
they sometimes get written onto my terminal as messages.

>How-To-Repeat:
In one terminal start tail -f /var/log/messages

On the console of the box start
  while true; do
    hexdump /kernel
  done

Watch the messages. This problem does not happen when the hexdumps go
to xterminals. I have no serial console to see if that is affected.
>Fix:
Dunno.
