You can prevent it from panicing by setting "panic_on_oops" to 0
echo 0 > /proc/sys/kernel/panic_on_oops

Unfortunately, there is no boot-prompt option for this;
there should be a __setup(panic_on_oops) added to kernel/panic.c

As to actually recovering from that error-- you might try applying
one of the earlier posted EEH patches; it should work.  These earlier
patches aren't in the mainline kernel because they have deficiencies.

I'm supposed to be re-writing the code to make an EEH patch that is
generally acceptable as a real patch, but am currently snowed under 
with other activities.
