A kernel version 2.6.38.6 patched with your two patches modifying only
arch/x86/kernel/cpu/amd.c starts and runs without problems on the affected
system with a AMD Turion 64 processor. The system is pure x86_64 (Debian
Release: wheezy/sid) with gcc version 4.6.1 20110428 (prerelease) (Debian
4.6.0-6) and GNU C Library (Debian EGLIBC 2.13-4) stable release version 2.13.
The only obvious difference I see is the message "using C1E aware idle routine"
in dmesg.
