Public bug reported:
Binary package hint: acpi
On my Vaio SR17 laptop, when I run a CPU-intensive process (like
compiling a large program), eventually kacpi_notify always begins to
take 85% or more of the machine's CPU. I can't kill kacpi, even with -9,
and I can't even shut down gracefully: the machine gets through most of
the shutdown sequence and then sits there with the CPU still spinning,
and I have to pull the power plug.
This machine worked fine under Breezy. Please, is there any way I can
disable kacpid, or control its function? I don't think it's doing
anything I need (CPU speeds and the CPU fan are controlled in BIOS on
this machine). Google finds tons of people having similar problems, but
nobody seems to know a fix. I don't want to disable acpi entirely since
ubuntu's excellent acpi suspend/hibernate support (in breezy, anyway) is
the biggest reason I prefer ubuntu on this laptop.
** Affects: acpi (Ubuntu)
