Title:
"ACPI PCC probe failed" message is an error message when it should be
debug
Status in linux package in Ubuntu:
Incomplete
Bug description:
[SRU Justification][Vivid]
Users of Ubuntu Vivid are seeing a seemingly alarming kernel failure
message "ACPI PCC probe failed" when in fact it is just a debug
message informing the kernel developers that a probe for an ACPI PCC
mailbox was not successful (which is just a debug only message) and
not a failure one needs to worry about. This message is asked about
frequently on askubuntu.com, so it is alarming quite a few users, c.f.
: http://askubuntu.com/questions/708215/1-037533-acpi-pcc-probe-
failed.
This fix landed in Wily, and the driver with the alarming message only
affects Vivid.
[Fix]
Upstream commit efd756daf4ddae3cec2404c4e0b680b7cfdd6a45 ("ACPI / PCC: Use pr_debug() for debug messages in pcc_init()")
[Testcase]
Boot a machine without the PCC feature, without the fix one sees the
error message in the kernel log. With the fix, this error is now a
warning. Note: This only affects Vivid.
