Hello,
I am using an embedded XScale board. I am trying to
run Linux 2.4.21 kernel (with some patches to make it
work on this platform). I have cross-compilation
tools.
The kernel boots up pretty much all the way, gets an
IP address from DHCP, mounts nfs root, however panics
during Freeing init memory (I think). Naturally I
don't have access to the ksyms file, so the ksymoops
utility for this platform is not very helpful. Can
someone please suggeset ways/steps, or if there are
pointers on the net, to debug the oops trace. I am
pasting the output of the serial port below.
Can someone please tell me what the phrase "In
interrupt handler - not syncing" means, specifically
the "not syncing" part.
Thanks in advance,
Ahmed.
