When starting new, pick something new, i.e. 2.3 right now. Only if you
have good reasons, staying at older versions is recommended.

Is CONFIG_XENO_HW_SMI_WORKAROUND selected? What does the kernel output
tell you about if it's working? Do you have an ICH7 chipset on your

2.2.x doesn't)... :)
If this all doesn't help, have a look at this tool:

In any case, please give a feedback on the outcome.
