Hi
We've developed a custom board deploying a mpc 855 (ppc). With kernel
2.4.22 and linuxppc-2.4.22 patch from /pub/linux/kernel/ports/ppc/2.4
as well as some platform specific adaptions we are able to boot and use
2.4.22 succsessfully. Unfortunately, jffs2 has a nasty gc-bug so we want
to upgrade to 2.4.23 and maybe later to 2.4.31.
It was possible to apply all our custom patches to 2.4.23. No ppc-port
patch was applied as we assume this was incorporated into 2.4.23.
Unfortunately we can not boot anymore. Using BDI, a md xxxx log_buf and
some printk debugging reveals "Decrementer frequency..." as last
message. Therefore, kernel hangs when jumping into console_init in main.c.
Our hardware did not change in the meantime nor did our custom patches.
Any clues on how to proceed/chase down this bug? Patch 2.4.23 was a
rather fat one to start tracking... Supposedly, we're encountering a
memory bug, but switching on memory checks in the kernel hacking section
didn't help neither.
Any help is most welcome. Please CC me as well.
René
