Hello,
I am having many problems with the asus a7v266 motherboard, and its IDE
controller. It seems to be corrupting data transfers to and from my
single 40 gb Quantum Fireball hd.
I ran Robin Miller's Data Test Program (dt) from
http://www.bit-net.com/~rmiller/dt.html. It reported errors after a few
tests.
I had DMA enabled via hdparm,
I was running kernel 2.4.18.
These occurrences seem to be common with my chipset, or others by
VIA.
I have been running the same motherboard for about 3/4 of a year,
with none of these problems until last week, why would that be?
Is this a bug in the motherboard? or is it the way Linux handles it?
Anyways,here is the output of dt:
# ./dt of=../test limit=1g min=500k max=2000k procs=2 log=dtlog runtime=1h

--END OF OUTPUT--
Sometimes, when I altered the run-time parameters I would get complete
kernel crashes, leaving a message similar to the following:
Assersion Failure in __journal_file_buffer() transaction.c:1937
..
I don't really know how one may be related to the other, as I did not log
the complete output of the crash...
Thanks for your help,
-David
