Needless to say I do not have an secondary storage or an swap device, but I am running rootfs from /dev/nfs. System has only 4MB of ram. 2)When the system crasses it goes into the "Rebootting in 180 s" prompt, but fails to reboot, i.e. it goes into endless loop, like: Rebooting in 180 seconds..<0>Kernel panic: Kernel Mode Software FPU Emulation Rebooting in 180 seconds..<0>Kernel panic: Kernel Mode Software FPU Emulation Rebooting in 180 seconds.. In the reset vector there are probably some corrupted data that looks like FPU instuction that triggers the FPU trap. This makes me think that the Interrupt vectors are somehow screwed. Do you guys recognise this behaviour? System is embedded 2.2.5 with mpc 823 CPU 4MB of Ram. Thanks, K.D. [[ This message was sent via the linuxppc-dev mailing list.
