Subject: Re: kern/26825: mpt driver hangs during 2.0 install

 Another data point (2.0.1 kernel) -- untarring a 2.0.1 binary
 distribution to an ffs mounted with softdep gives me:
 
 # sh install-i386-sets.sh
 Compare MD5 checksums...
 base.tgz         -- set OK.
 comp.tgz         -- set OK.
 games.tgz        -- set OK.

 misc.tgz         -- set OK.
 text.tgz         -- set OK.

 Now reboot, then mount sources to /usr/src
 and run "env USETOOLS=3Dno etcupdate -w100 -v -a -l".

 [machine locked]
 
 -- the machine has 512 MB RAM and unpacks the tarballs very quickly to
 buffer cache. When the cache gets flushed, the LSI20320 jams quickly.
 
 Unfortunately, we've got four machines equipped with those controllers.
 If it helps, I could run test kernels, or provide a remote login /
 serial console.
