Description

Upstream kernel + no_console_suspend for XO-1 is broken. Serial console is unusable on resume. This is because XO-1 powers down the serial chip during suspend, and Linux doesn't make any attempt to resume it under this configuration.

Commit b9ce1d7e1f2c56da8 was applied to olpc-2.6.35 as a hack.

This ticket tracks a real upstream fix, possibly based on http://marc.info/?l=linux-serial&m=129138711106604&w=2
