Hello,
Im having problems with DMA transfer on Linux, for an ADC card. The
card is AxiomTek AX5621H (ISA), and can use DMA channels 1 and 3. I
tried both the channels, but the DMA transfers are irregular (i.e.) at
different speeds (which of course is not acceptable, since that
application is time critical). The device driver (which I wrote) seems
to work fine for all the other systems I tried it on. But this problem
occurs only on one particular model of computer (Chino-Laxsons Pentium-4
boards). I tried another system with the same configuration, but the
same resulted. After some time of execution, I get the kernel panic
screen, which says the CPU context is corrupt. Please help me with this
problem, as I need to get this driver working somehow on the P4 systems.
I tried the Redhat-9 kernel (2.4.20-8) and the debian kernel too
(2.2.20).... gave the same results.
Thanks in advance,
Harish.
