I don't want to get into or repeat a *very lengthy* discussion here, but this
is an artifact of EGCS and inline functions.  It basically boils down to the
fact that running without -On and inline functions (the way they are used
by the Linux kernel) just doesn't jive.

Is there some reason (other than your instability which I understand) that
you want to do this?  BTW - Linux 2.2.1 is incredibly stable on my PreP box,
so I have little fear in the compiler, at least for the non-PowerMac specific
stuff.

Thanks for the answer !

My problem is that I have regural crashes (kernel panic) with recents kernels
when I run Xpmac or XF68_FBDev. (see January archive)
It seems that I am the only people in this situation on this earth, so I am
trying to solve my problem with my own and humble capacities.
Since I am not a guru neither an expert, I just play with only tuning
capapbilities I got. Compiler optimiser is one of them.

By the way, I have not crashed since I run with the 2.2.1 kernel compile with
-O1 option. Ok It is just 10 hours old but it smells better than before.

I agree that it could hide some other problems like hardware ones... but if the
problem is a timing problem with hardware, running a little bit slower could
help. In fact I am more or less convince that my problem is linked to harware
due to the fact that I have never succeeded to make the virtual memory
working correctly with MacOS (7-5-3 to 8-5-1). But if I send my old 8500/180 to
repair it will cost me the price of a new iMac... and I am even not sure that it
will work correctly after.

Sounds like your hardware may be a bit shakey...

What bothers me is that it was working like a charm with 2.1.24 (just normal
shut down for hollidays and no crash for weeks). The point is that it seems
that X seems to work slightly faster with recent kernel ... Is it just an
illusion ?

Indeed the newer kernels are quite fast!  Also, 2.1.24 is pretty old, a lot
changed in ~100 revision...

Hopefully someone closer to the PowerMac side can help more.
