Hi all,

   I'm seeing the "timeout waiting for DMA" problems that I've noticed
several others are running up against.  I have a UDMA-66 drive that I
have _full_ of data.  After some amount of disk activity (some can be
very little [a few minutes], or a long time [hours]), I get the
following on the console (copied the best I can):

ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdc: irq timeout: status=0x50 { DriveReady SeekComplete }
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: DMA disabled
hdb: DMA disabled
hdc: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdc: irq timeout: status=0x50 { DriveReady SeekComplete }
ide0: reset timed out, status=0xd0
hdb: status timeout: status=0xd0 { Busy }
hdb: drive not ready for command
hdc: timeout waiting for DMA

   The IDE controller in question is a Promise 20262 Ultra/66 controller.

   I'd appreciate any suggestions that I can get at this point.  I've
spent lots of time building the 2.4.2 kernel, and that didn't seem to
help.  I had previously been using the 2.2.17 kernel with the latest
IDE patch from people/hedrick to no avail.

   At this point, I'd be more than happy to test out new IDE drivers,
if that's what things take.

   Included below is some info from my system.  I'm not sure what's
useful, so I probably put more here than I needed to.  If there's
something missing, please let me know.  Also, I'm not subscribed to
the list, so a CC back to me would be appreciated!
