Hi Julian,

Point taken about the "Won't Fix" - I will change it back to "In
progress":  was premature of me, so apologies for that. The difficulty
we have that if there is something wrong in the DSDT and the kernel uses
this to configure the hardware, then we are at the mercy of the DSDT to
be correct, else we get these sort of issues. I will investigate why
this does not occur with gutsy.

As for the yenta_socket, I will dig into this, but again I suspect that
if it is being misconfigured from the BIOS APIC settings, then we are
going to see problems unless we fix the BIOS or tell the kernel to
ignore the BIOS.

I agree with the statement that ' "Linux should run on un-modified
firmware", this may be considered as a kernel or ACPI bug' - if it's an
ACPI bug we are at the mercy of the manufacturer getting things right.
If it's a kernel bug in yenta_socket or the APIC handling then I will
look into an appropriate quirk to fix it.

Colin.
