SubjectRe: [PATCH] 2.6, 2.4, Nforce2, Experimental idle halt workaround instead of apic ack delay.
Yes, but for me the temp diff in Celsius between idle and load for the CPU
is almost 20 degrees. This has a dramatic impact on the case temperature
when it is closed because I haven't added fans in the top of the case yet.

So you see I value the disconnect quite a bit. Maybe when I get better
cooling I will disable it altogether in the BIOS so this headache will
disappear forever ;)
