Description kfm 2012-06-25 01:20:58 UTC

Created attachment 316205 [details, diff]
acpi-apei-fixup-register-definitions.patch

"Many firmwares have a common register definition bug where 8-bit access width is specified for a 32-bit register. Ideally this should be fixed in the BIOS, but earlier versions of the kernel did not complain, so fix that up silently."

I ran into this issue on a HP ProLiant N40L Microserver. It's more of an annoyance than a hindrance because it floods out the kernel ring buffer over time. Please consider the attached patch for 3.4 trunk.

Amending subject as it it's still needed as of 3.5-rc4.

Hi, Kerin.  Sent upstream?

Comment 3 kfm 2012-07-20 22:36:29 UTC

I don't see it in Linus' tree so it would appear not. I'll chase it up.

Comment 4 kfm 2012-08-10 19:14:59 UTC

It landed in 3.4.8 and 3.5.1.
