that is interesting. I suppose the kernels are about the same? I wonder
why one works better than the other...

I undertand. It is a pity though. Unfortunatately I don't have the
knowledge myself to fix it although I'll try my best at testing or
giving information about what is wrong.
I have used 3.3 succesfully for a long time, being 3.5 broken on my box.
I have now completed the install of 3.6 and that one indeed works fine.
The kernel seems to work pretty well and I might even thing that it is
faster. But some operations have dramatically slowed down (login, sudo)
I guess there are more secure routines now that use CPU more heavily.
From the scarce knowledge I have of 68k processors I even wonder that
68040 works and not 68030 since the first is more of a subset of the
second (given a 68882 FPU of course). Or is some support of the chipsets
used in the 68030 broken ?
Do you have a 68030 yourself or have the faintest idea of what is broken
?

cheers,
