I attempted the following in kernel config file:

wd*     at atabus? drive ? flags 0x0fac

cd*     at atapibus? drive ? flags 0x0fac

To force PIO mode 4 and DMA mode 2 (disabling UltraDMA).  This had no 
effect... still bogus intr problem.


Then I tried disabling DMA altogether, with "flags 0x0ffc" on wd and 
cd.  This also had no effect... still bogus intr problem.


By breaking into gdb (ctrl-alt-esc) as soon as the problem starts and 
entering "dmesg", I could see it never seems to get to attaching wd*.  I 
suppose that's what it's trying to do when the "bogus intr" occurs.

What can I do to help troubleshoot this problem?
