Installed the 3-13-97 snapshot binaries on a 5k/240.  Setup as a HTTP proxy
server.  Supped current kernel sources and built a 2.1D kernel.  Ran fine
until we put it into production.  Within 2 hours it crashed hard.

We are getting a lot of the following errors logged to syslog:

Mar 27 19:30:57 webcache /netbsd: asc: DMA_OUT, fifo resid 1, len 0, flags 0x30
Mar 27 19:31:28 webcache last message repeated 2 times
Mar 27 19:33:02 webcache last message repeated 7 times

Also got a lot of binary data written to syslog and thousands of lines
like:

Mar 27 16:54:31 webcache /netbsd: s
Mar 27 16:54:31 webcache /netbsd: g
Mar 27 16:54:31 webcache /netbsd: Z
Mar 27 16:54:31 webcache /netbsd: N
Mar 27 16:54:31 webcache /netbsd: D
Mar 27 16:54:31 webcache /netbsd: 8
Mar 27 16:54:31 webcache /netbsd: -
Mar 27 16:54:31 webcache /netbsd: !

The only panic messages we could find where:

Mar 27 19:17:10 webcache syslogd: restart
Mar 27 19:17:10 webcache /netbsd: mode = 0100600, inum = 42501, fs = /usr/tmp/pr
oxy
Mar 27 19:17:10 webcache /netbsd: panic: ffs_valloc: dup alloc
Mar 27 19:17:10 webcache /netbsd: syncing disks... 11 11 5 done


The machine would not reboot until we had newfs'd our proxy volume,
cleaned everything up manually.  We're running at the moment on
Jonathan's 2.1D kernel he published with the snapshot.
