Bug#394049: Problem also occurs with kernel 2.4
Hello,
these error messages also appear with kernel 2.4 (in my case,
kernel-image-2.4.27-1-k7). As far as I understand it, the reason for
this is that the kernel tries to set a DMA mode that is too fast for the
hardware to handle. On my box, the DMA mode is initially set to UDMA100
which results in these errors, and the kernel consequently lowers the
DMA mode to UDMA33. Interestingly, this happens during most, but not all
bootups. In some (seemingly random) cases the kernel initially selects
UDMA33 and the errors stay away.
I am getting these errors since I upgraded to the 2.4.27 kernel; before
I was running 2.4.24 which always selected the UDMA33 mode right from
the beginning.
As far as I can tell the system works well in spite of the error
messages; still it might be a more clean solution not to boot with a DMA
mode set to a too aggresive value. Unfortunately, it does not seem to be
possible to set the DMA mode with a bootprompt parameter (or am I
missing something?)
Greetings,
Jan
