I have made a new patch set for Microchannel machines. It is available from

and should be installed on top of Linux-pre2.0.5. I have made the following
changes to the last complete distribution I am aware of (fourth.tgz

1) Small adaptions to make everything compile smoothly.
2) Removed MCA-specific shared interrupt support. SA_SHIRQ is supported
in the standard kernel.
3) Modified psaux.c, ps2esdi.c, and 3c523.c to use SA_SHIRQ on MCA
machines (this is untested).
4) Removed floppy.c patch, since the standard floppy driver now seems to
work even on PS/2 Models 95 (hallelujah).

I have also tried to share IRQ3 between serial.c and ibmtr.c (patches
available from web page). Sharing seems to work Ok until I close ttyS1
for the first time. The next Token Ring interrupt then causes the machine
to freeze. If you like to do some hacking....
