Hi Mike,

is your problem still present in kernel 2.6.16-rc1?

Hello
this is a repost since I have some new information for the Oops described 
below.

System:
        4P Opteron x86_64
        24GB RAM
        LSI SCSI-megaraid controller 320-2X
        Vanilla kernel 2.6.14 oops

Tested so far: (driver version is same in all kernels)
2.6.13 is ok. No Problems.
2.6.14 /w boot option mem=4G is also ok!
2.6.15-rc2 similiar to 2.6.14?

Hello,

sorry for using this big list of recipients, but I'm not sure, who of you 
might be the one, who is most interested in the problem.

I just booted vanilla 2.6.14 on a 4way Opteron (HP DL585) with 24GB RAM. 
Kernel was compiled with gcc 3.3.5.
MegaRaid is compiled into kernel.
While booting and initializing megaraid I get the Oops described in the 
following picture:
