I should mention at the outset something that appears to be different
between me and George.  My system hang is inconsistent; sometimes it
happens, and sometimes it doesn't.  When it hangs, I do cold boots
until I get a boot that works.

Now the latest:

Same for me.  To wit:

I found the setting ("Support for Ultra SCSI Speed") and it was already
Disabled.

I tried pulling down 1.11.2.16 and compiling, but I get:

../../pci/aic7870.c: In function `aic7870_attach':
../../pci/aic7870.c:450: `RESET_SCSI' undeclared (first use this function)
../../pci/aic7870.c:450: (Each undeclared identifier is reported only once
../../pci/aic7870.c:450: for each function it appears in.)
../../pci/aic7870.c: In function `load_seeprom':
../../pci/aic7870.c:563: `RESET_SCSI' undeclared (first use this function)

If you know specifically where that one is defined, I'll try pulling
that down, too... but I'm a little afraid of a "cascading #include
failure".  I may have to just sup sys again.

Based on George's results, I haven't tried this patch yet...
