Looks to me bad memory in one of the banks, try booting with less memory 
(remove Dimms).

I also saw this messages ( in a solaris kind of way) and that ended to be a 
bad cpu !

I don't know if there is a memtest for sparc, but the Sun hardware monitors 
its memory all the time.

Compiling kernel on Ultra-2

[Bas van den Heuvel]

Hello,

I'm having a hard time compiling a kernel (tried 2.4.19 & 2.4.20) with 
built-in raid support.

with modification of some files i can get it compiled correctly (the "debian" 
way). 

But after modifying silo.conf and trying to boot the kernel i get 

Data Access Exception at the boot prompt.

The old kernel boots ok (2.4.19).

I searched many archives and found out that I may need egcs64. I apt-get  it, 
but have no clue how to force building the kernel with this compiler (tried 
the update-alternatives as stated on the debian howto, but failed)

Anybody having a clue, or can show me "the" way ?

Thanks in advance,


Bas
