I don't mind the wait for memory being freed. Copying more pages with interrupts disabled would mean a higher chance for PMU lockup, won't it?
It's also possible that there is a bug and it just crashes :) Also, I do suspend devices before the page copy, and I quickly hacked a PMU sysdev that should suspend ADB interrupts (at least) so that should be fine, except if you have a brightness request in flight maybe ? The whole PMU suspend thing must be reworked I suppose. (And the battery monitoring thing "paused" as well, we must wait for async PMU requests, that is at least battery requests and backlight ones to stop) Ben. ** Sent via the linuxppc-dev mail list.
