FWIW, the irqrate-A1 patch from the -slb/-jam series kernels
(2.4.18-rc1-slb2 through 2.4.18-rc2-jam1 for certain) seems to make one of
my computers (a dual 1GHz PIII, Iwill DVD266-R motherboard) hang when I
access the floppy drive. I don't believe this happens on other
(uniprocessor, not SMP) machines I have here, although I'm not certain
about that. This is 100% reproducible.

This bug report is probably rather vague, but I probably won't have time
for anything more detailed or any debugging activities related to this for
several weeks, and I hope this report is better than nothing.

My box also hangs acessing the floppy. Strange thing is that it also
hangs without irqrate-A1. Will send an oops.

It could be one of the patches that comes before irqrate-A1 in the 00-90
numbering sequence that your patches use; I've definitely reproduced this
without any of the patches numbered higher than the irqrate-A1 patch.(In
my case, if I applied all of those patches except the irqrate one, I
didn't get the freeze. If I applied all the patches up to the irqrate one
after, then I got the freeze.)

I vote for the sched-O1. The mount never gets rescheduled ????

Just one problem: I can reproduce this without sched-O1.

In fact, all I need is plain 2.4.17 + irqrate-A1. That's it. That's all I
need to get floppy accesses to hang 100% of the time. 2.4.17 without
irqrate does not have this problem.

(I haven't tried getting an oops with sysrq yet.)

For that matter, 2.4.14-pre7 (the earliest that I can apply the irqrate-A1
patch to without rejects) + irqrate-A1 also causes the floppy freeze for
me. By "freeze" I mean my mouse pointer stops moving for me in X and I'm
unable to switch virtual consoles.
