Presumably acpi_ex_extract_from_field() fed zero into (the misnamed)
ACPI_ROUND_UP_TO().

I'll ask Rafael and Maciej to track this as a post-26.33 regression,
thanks.



the patch here fixes it for me:ACPI: EC: Limit burst to 64 bit
https://bugzilla.kernel.org/attachment.cgi?id=25962

hm. I wonder how you go from a bugzilla attachment back up tot he bug
to which it is attached?

I don't know.. maybe backwards thinking(me lefthanded people
suffer from things of that nature).


Oh well. Alexey, I trust that patch is in the 2.6.34 queue?

Thanks.



cool..
