| |
This is a manually decoded oops from 2.2.19 - the top of the oops ran off the serial console buffer (sigh) and there was nothing in the files, so I decoded the stack manually with 'ksymoops -A' on every stack entry. This gives a looping stack like below (I've this is a representative sample from the end of the oops output. Note the last section is the only but with the mmput in.
Any idea what could cause this (& why it didn't just Oops once, and stop). I presume it continued in a cyclic manner until the stack filled up and then everything died.
