I use three boxes, all running most recent CURRENT. Only one box d= oes work and boot with the option mentioned above in the kernel. The other two don't, th= ey stop at printing something about HPET timer initialisation and stop - forever. I did not digg deeper into it, but there is something strange: Both failing boxes have CPUs with two cores, four threads. One is a noteboo= k with an Haswell 4200M, the other is a i3-3220. The i3-3220 box has a motherboard ASROCK Z77-Pro4 (UEFI on this crap is not= working), 8 GB RAM (2x 4GB), lates firmware from 2013.=20 The working box has an ASROCK Z77-Pro4 M (mini ATX size mobo), 16 GB RAM (2= x 8GB), but a 4 core/8 thread XEON IvyBridge E3-1245 V2. The firmare is the latest, from = 2013. The box is running well with the option EARLY_AP_STARTUP set.=20 At a first glance it looks like the failure is dependend on the CPU count ;= -) I have also a small PCengine APU 2C4, AMD Jaguar CPU with 4 core/4 threads which is abo= ut to be tested also with the most recent CURRENT and the option in question set - but it t= akes time. Just for the record, my apologizes if someone feels disturbed from naive ob= servations. Kind regards, oh --=20 O.
