------- Comment #20 from [EMAIL PROTECTED] 2008-02-10 14:40 -------
patch in comment #12 shipped in Linux-2.6.24-rc22 as two patches:
commit b3b233c7d948a5f55185fb5a1b248157b948a1e5
Author: Alexey Starikovskiy <[EMAIL PROTECTED]>
Date: Fri Jan 11 02:42:57 2008 +0300
ACPI: EC: Some hardware requires burst mode to operate properly
Burst mode temporary (50 ms) locks EC to do only transactions with
driver, without it some hardware returns abstract garbage.
commit 3e71a87d03055de0b8c8e42aba758ee6494af083
Author: Alexey Starikovskiy <[EMAIL PROTECTED]>
Date: Fri Jan 11 02:42:51 2008 +0300
ACPI: EC: Do the byte access with a fast path
Specification allows only byte access for EC region, so
make it separate from bug-compatible multi-byte access.
Also do not allow return of garbage in supplied *value.
So it looks like battery information on these systems is now
correct when available, but its availability is intermitant.
So we'll keep the report open to address that issue.
