Re: ext3fs errors with kernel 2.6.18 but not with 2.4.27

Perhaps I misunderstood, but I thought he got the errors with the old
kernel (and had for a long time) but they did not trigger a filesystem
check. My hunch was that the 2.6.x IDE driver (or ext3 driver) is handling
the error condition in a different way. Perhaps not retrying at all on the
CRC error, or maybe having a shorter time-out on the retry, who knows...

If he only gets the errors under 2.6.x and not 2.4.27 then it looks more
like a driver issue. Perhaps his 2.6.x kernel is using the new 'merged'
SATA+PATA subsystem to handle his PATA drive instead of the old ATA/ATAPI
driver and that is causing the problem.

It seems like I wasn't clear. Let me try to clarify:

On 2.4.27, I get the CRC errors (not at boot time, later, and all the
time thereafter),
and I've been having them for many years. I mentionned just in case
there might be
a link with my problem. Otherwise, I am not trying to solve this
particular problem.

On 2.6.x, at boot time, errors are reported on the initial filesystem
check. I do
not know if I still have those CRC errors.

I will try to see tonight or tomorrow if I can manage to get some logs
as Douglas
suggested. I will also try to look at what driver is in use also. Looking at my
config-2.6.18 file:

http://www-etud.iro.umontreal.ca/~duranlef/linux-config/config-2.6.18

it's hard to guess. All I know is that all SATA support is disabled.
