SubjectRe: [Bug #10724] ACPI: EC: GPE storm detected, disabling EC GPE
Well, I read in another thread that there are some issues with this
patches. Anyway, I'm now running .26 with your patch since yesterday,
tried 3 suspend/resume cycles and 2 hibernate/resume cycles and
everything seems to be fine.

It looks that it's really solving the problem for me.

Thanks for your work. Cheers,
Fabio
