Rev 1.35 of src/sys/i386/isa/ipl.s, which I just committed, should
fix the boot lockups.
Many thanks for Alain Thivillon who was able to catch it in the act
with DDB and narrow the problem down to doreti looping on astpending.
To anyone I asked to try backing out the recent patch with an explicit
revision checkout, please remember to blow away your src/sys/i386 subtree
and check it out again so those files are not locked to a fixed revision.
I am hoping that this will also fix Bob Bishop's reported boot lockup.
The slow-response and jerky mouse problem should also be fixed.
