Dear Greg,

have you received this patch? Just wondering because I have not heard something about this anymore from your side. Please do also have a look at

[PATCH 2/2] w1: Disable irqs during 1-wire bus operations, extend 1-wire reset pulse

Both patches have already been signed by Evgeniy Polyakov.

Thanks and with best regards,

Markus Franke

They are in my queue to apply after 3.4-rc1 is out as they came in after the merge window closed for my trees.

It applies to the current linux kernel git tree.

It's corrupted somehow and doesn't apply at all :(

Care to redo this one, and your 2/2 patch, against the 3.4-rc2 release and resend it, with Evgeniy's acks, so that I can apply it? Please ensure that your email client doesn't mess it up again (hint, it is adding spaces at the front of the line of some parts of the diff.)

thanks,

I don't have a clue what might go wrong within my email client. Would sending it as an attachement be an option? If not I might have to switch to another client.

Used Thunderbird with external editor (vi) now, sent the patches to myself and applied successfully. Hope it is in a shape which can be accepted now.
