I have just tried burning a data CD using Linux 2.4.20-SMP (1 GB, devfs,
dual 933 Coppermine PIII) plus the following patch:

I grabbed that patch off the list last week; it looked like a good idea
for an SMP system. Anyway, a dummy write worked fine and so I tried
burning for real:

Unfortunately, the process hung briefly after writing the "Track 01"
message, and then wrote the following message into the log file:

Now the machine recovered and the data CD *seems* to have been written OK,
but I am obviously concerned about the "hiccup" in the IDE subsystem. (I was
using the ide-scsi module to do all this.) The machine was not doing anything
besides burning my CD-RW at the time.

And this is what the SCSI layer was looking like:

I haven't tried reenabling DMA on this drive yet. Previous experience with
reenabling DMA after it has been explicitly disabled suggests that it might
hang the machine! This is what the IDE settings for the drive used to look
like:
# cat /proc/ide/hdd/settings
name value min max mode

bios_head 0 0 255 rw

Does anyone have any idea why the DMA failed, please? Is it a known issue
with 2.4.20? If anyone would like any further information then please let
me know,
Cheers,
Chris
