Hi!

Ok, 7c0... is innocent. Reverting not only the mdelay, but also rest
of drivers/acpi/ec.c patch fixed the
"rc6-breaks-backlight-in-X-over-lid-close", good.
Can you clarify a bit?

Do you mean that the full revert of 2c81ce4 that already got committed is sufficient for you, or do you need to totally undo everything we've done to ec.c since -rc5, and thus also to revert the _other_ revert we did (in 4af8e10a6c57e7292862bd1703712f0565c7e429)?

I did some more testing, and realized I was wrong. We need to totally
undo everything we've done to ec.c since -rc5... (that has small
sideffect of brightness up/down keys no longer working -- regression
since 2.6.24, but saves us from "backlight gone after
closing/reopening lid" which is _NASTY_ regression from 2.6.25-rc5).

ACPI sucks.

I.e. this patch:


Revert ec.c to 2.6.25-rc5 state:

* this fixes backlight after closing/reopening the lid while in X on
thinkpad x60

* unfortunately it breaks fn-home/end keyboard brightness control
It should also break volume up/down/mute keys. Essentially all the keys on Thinkpad.
And it would also be regression to 2.6.24 level.

Alex.
