I'm experiencing serious problems with DMA (even normal DMA, not UDMA)
on recent versions of -STABLE. Here's an excerpt from messages; kernel
#3 is a recent -STABLE (yesterday's sources), while kernel #2 is
3.2-RELEASE. The config file for both is identical.

I can confirm problems with DMA
My fault
I accidentally replaced a PAGE_MASK with a PAGE_SIZE.
the resulting bug only changes teh behaviour on unaligned pages
which are only possible on the raw device.
(e.g. fsck)
the Cyrix 5530 we used to test has a bug where we cannot do unalligned
transfers by DMA anyhow, so we never hit

Fwiw, I sometimes (mostly after a warm reboot) see:
mmm dd hh:mm:ss hal /kernel: ata1: unwanted interrupt 1 status = ff
immediately followed by a similar Fatal trap 12: page fault while in kernel
mode. Last time, the current process was swapper. Next time it happens I'll
write down the details.
