+ <p>
+ The T400, when run without CPU microcode updates in coreboot, currently kernel panics
+ if running QEMU with vt-x enabled on 2 cores for the guest. With a single core enabled
+ for the guest, the guest panics (but the host is fine). Working around this in QEMU
+ might be possible; if not, software virtualization should work fine (it's just slower).
+ </p>
+ <p>
+ On GM45 hardware (with libreboot), make sure that the <i>kvm</i> and <i>kvm_intel</i> kernel modules
+ are not loaded, when using QEMU.

+ The following errata datasheet from Intel might help with investigation:
