Re: floppy0: Unable to allocate DMA memory

Hello,

I've upgraded one machine to 2.0.32 5 days ago, and have been testing
it. It appears that the floppy drive functions are fixed, and I haven't
seen (yet) any of the other "glitches" that others have seen with the
new kernel.

(cross my fingers)

I have noticed that sometimes, I still get a DMA error with the floppy
and it says /dev/fd0 isn't a valid block device. However, I can execute
the same command right away and it will work the second time (and a
third and a forth, etc).

Still not as reliable as 2.0.29 was, but better than 2.0.30.

P.S. If that's not enough reason to change kernels, 2.0.32 fixed a lot
of the memory allocation problems too I've seen. And Apache runs much
better now. Whether you go forward or backwards, I'd advise moving off
of 2.0.30.
