Dump Card State Begins ...

*sigh*

Today I crashed the system running 4.8 after it's been
doing "make buildworld" all through the night without a hitch.

At least I now have a way to reproduce the error within seconds:

I have 1 disk connected to each of the onboard controllers
(mpt0, mpt1) of this Tyan S3022 board.
When I start "iozone -a" on one of the disks the system running 4.8
keeps running - where the system running 5.1 crashed occasionally.

As soon as I start a second "iozone -a" on the second (!) disk
(and, therefore, controller/channel), the system crashes
immediately. (4.8, no tests with 5.1 yet)

How do I enable pretty printing for the mpt controller?
Does "options AHC_REG_PRETTY_PRINT" apply to the other
drivers as well? Which FreeBSD version should I use for
testing?

Thanks,
Patrick
