	[jocke at filserver /storage/tmp]$ i=0;while [ $i -le 10 ]; do dd if=/

I let it run for a while, and checked back later.

<http://home.komsys.org/~jocke/dmesg_mps0_freebsd-scsi_6.txt>

	hw.mps.0.debug_level: 0
	hw.mps.0.allow_multiple_tm_cmds: 0

	hw.mps.0.chain_alloc_fail: 786

As you can see, I didn't do anything about the 'MPS_CHAIN_FRAMES'- 
value after I pulled the latest version. I could change it, but I  
guess this only would get rid of the 'out of chain'-messages, and not  
really solve the underlying problem.
