SubjectBug in 2.0.x - Unable to allocate DMA memory
I'm not sure if it's in all 2.0 versions but I definitely think it's
a bug. IMHO Linux should be able to preempt some memory pages from
other processes to fulfil the request for DMA memory. What do you think?

# mcopy rtc.c a:
floppy0: Unable to allocate DMA memory
Can't open /dev/fd0: No such device or address
Cannot initialize 'A:'
Bad target
# free
total used free shared buffers cached
Mem: 63132 59804 3328 9500 5856 27856
-/+ buffers: 26092 37040
Swap: 48640 8888 39752

You'll either hit it with a hammer or get a splinter in it.
