Hello,
Starting with kernel 2.6.17-rc1 (also happens with 2.6.17-rc2), second
logical-CPU of my Hyperthreading system no longer boots.
I tracked up changes in APIC code, and it appears reverting commit
7c5c1e427b5e83807fd05419d1cf6991b9d87247 fixes this bug.
See both dmesgs, and kernel configuration attached.
Feel free to ask me if you need other informations.
Please CC me as I'm not subscribed to LKML.
