the following patch was just integrated into master: commit 1896e2a19c848725a30833eabe0f12b10a714527 Author: Rudolf Marek r.marek@assembler.cz Date: Tue Apr 24 16:01:24 2012 +0200
Make timestamp collection conditional in hardwaremain.c
Otherwise it breaks 486 boards without RDTSC, ending with exception 6.
It ends like this on bifferboard:
Jumping to image. Unexpected Exception: 6 @ 10:001007e3 - Halting Code: 0 eflags: 00000016 eax: 001001fe ebx: 00100118 ecx: 00000000 edx: 00108e00 edi: 0010aaf8 esi: 00000000 ebp: 00117ff4 esp: 00117fd8
Please keep in mind 486, dont use rdtsc/cpuid in generic code, or if you do make sure make it non-default option.
