"kernel + gcc 4.1 = several problems" / "Oops in 2.6.19.1"

[Udo van den Heuvel]

Hello,

I just read about the subjects.
I have a firewall which has some issues.
First it was a VIA CL6000 (c3).
Now it is a EK8000 (c3-2) with different power supply, RAM and board of
course. Still I see strange things sometimes. Crashes, hangs, etc. Now
and then. Not too often.

I have in .config:
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
CONFIG_MVIAC3_2=y

Does this mean the issue applies to my own kernels?

Udo

It could be.
Or it could be something completely different.

If the same kernel compiled with gcc 3.4.6 works fine, you might run 
into one of the mysterious problems with gcc 4.1.

It could also be hardware problems (e.g. try running memtest86 for a 
longer time).

Does the machine hang completely, or is any useful information like e.g. 
an oops available?
