Hi, I am currently working with an MPC8349ITX board and I have some trouble with the kernel as soon as it reaches userland.
If I boot the kernel with all the memory (256MB) available (no mem=... on the command line), I get random freezes or random kernel panics. Some times it won't even run init. Some times it will panic badly if I try to put some pressure to the system (stress --cpu 256). Some times it will hang immediately after logging in, ... If I boot the kernel with mem=64M, these freeze and random panic disapear and I am able to run the stress program without any problems. I have had this strange behaviour on both kernel 2.6.20 and 2.6.22 with mpc834x_itx_defconfig (both from kernel.org) (ARCH=powerpc). I am inclined to say that it is not a broken RAM chip problem because if I use a 2.6.17 from kernel.org with all the RAM available (ARCH=ppc) configured with mpc834x_sys_defconfig (there was no defconfig for the itx board on this version) everything runs fine and I am able to run the stress program without any problems. The panic does not happen very often, 90% of the time, the board hangs and stops responding to ping. When a panic do happen it is almost always in a different place. Does any of you have met this problem before ? If you have any clues about what is hapenning I'd be glad to hear about it :) Thank you for your attention, Regards, -- Nicolas Schichan _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
