DSISR = data store interrupt status register. DAR = data exception adddress error. MSR = machine state register http://www.mot.com/powerpc Click on "Library". The programming environment manual for 32 bit procs is where you should start looking. http://e-www.motorola.com/brdata/PDFDB/docs/MPCFPE32B.pdf Page 6-22 (p 242) Different processors may have other bits set in these registers. If something isn't listed, you'll need to look it up specifically for the processor in question. --Steve On Thu, Mar 13, 2003 at 11:03:31AM -0700, Brian Daugherty wrote:

hi,

I'm trying to debug a kernel panic. I'd like to lookup the meaning of

the

codes contained in the DSISR, MSR and DAR.

Exception state (sv=0x0DC62C80)

PC=0x90000E2C; MSR=0x0000D030; DAR=0x0DCDB000; DSISR=0x42000000;

LR=0x0001

Can anybody point me at some on-line powerpc docs which would help out?

thanks,

brian
