My patch still applies, but #10919 makes it obsolete. My patch fixed a bug that shows up in polling mode. #10919 kills polling mode. I've tested v2.6.26 + #10919 and it works fine (except for spamming the kernel log - please read my Bugzilla comment). It appears that interrupt mode suffered from a race which is very similar to my original problem. If two GPE interrupts arrive before the workqueue runs, then the second interrupt will be ignored because EC_FLAGS_QUERY_PENDING is still set. This will happen with any EC if interrupts are very close together, right? I think my patch also fixes this theoretical problem. But I'd rather you took over on this. I was already confused by ec.c in v2.6.26, and with #10919 I understand it even less. E.g. why is ec_switch_to_poll_mode() still present; what does it do now do_ec_poll() is removed? I'm happy to work on this with you, but I'd need to be able understand the code first :-(.
