ACPI / EC: Restart transaction even when the IBF flag set
BugLink: http://bugs.launchpad.net/bugs/1186062
commit 28fe5c825f8e15744d04c7c1b8df197950923ecd upstream.
The EC driver works abnormally with IBF flag always set.
IBF means "The host has written a byte of data to the command
or data port, but the embedded controller has not yet read it".
If IBF is set in the EC status and not cleared, this will cause
all subsequent EC requests to fail with a timeout error.
Change the EC driver so that it doesn't refuse to restart a
transaction if IBF is set in the status. Also increase the
number of transaction restarts to 5, as it turns out that 2
is not sufficient in some cases.
This bug happens on several different machines (Asus V1S,
Dell Latitude E6530, Samsung R719, Acer Aspire 5930G,
Sony Vaio SR19VN and others).
This is included in UBUNTU: Ubuntu-lts-3.5.0-34.55.
** Changed in: linux (Ubuntu)
Status: Won't Fix => Fix Committed
