Hello,
I have built Yacto-2.0 (Jethro) for RZ/G1M board. Board is coming up fine but got some kernel traces and not able to bring up display. With Yacto-1.6(Daisy) everything worked fine with same board and display. Kernel trace I am getting is as follows:
WARNING: CPU: 0 PID: 1183 at /home/vijay/yacto_2.0/rz_build3/build/tmp/work-shared/skrzg1m/kernel-source/mm/page_alloc.c:6798 free_contig_range+0x80/0x94()
2250 pages are still in use!
