I noticed the problem while re-basing the 2nd patch here, which I decided to now re-post despite the original discussion on v1 not having lead to any clear result (i.e. the supposed "leave Dom0 handle the RTC" has never materialized over the past almost 5 years). 1: restore pv_rtc_handler() invocation 2: detect CMOS aliasing on ports other than 0x70/0x71 Jan
