Greetings,

I received the below upon first poke of firefox icon after a resume.  

See attachment (evolution refuses to inline it).

Hi.


Are you able to reproduce it reliably? Failing that, could you try
enabling some the kernel configuration options that help with debugging
memory corruption (slab corruption checking in particular will probably
be the most useful thing here).

Regards,

Nigel

No, it's a never before seen event.  That said, I have had a couple of
dead box after resume events with other kernels in the last few months,
so I may have had corruption of a more deadly variety.  Unfortunately,
when I'm resuming, my serial console box is almost guaranteed to be off.

Rebuilding this particular kernel with slab debugging would probably be
a waste of time since stable kernels get very little runtime here, but
I'll re-add it to my config for test kernels just in case a survivable
event should happen.

Hi.


Thanks, Mike.

if you have dead serial console, or no serial console at all on you
laptop. Probably you can try the alternative of firewire with

Ah,  linux S3 resume is still a problem.

Is it repeatable? You may want to try with smaller set of
modules... prism54 is quite unusual...

Nope, rogue event... so far.  Prism54 is my wlan card.  (useless dang
thing, can't convince it to do encryption)
