None of the above worked, so further investigation is needed. 45610 3 cristian.iorga 2014-09-15 08:13:45 +0000 During the course of the investigation, I was not able to reproduce the issue for any other qemu machines. I tried with qemux86, qemux86-64, qemumips. 47381 4 cristian.iorga 2014-12-04 19:08:31 +0000 tmp/work/qemuppc-poky-linux/core-image-sato/1.0-r0/temp/log.do_rootfs details: NOTE: Running intercept scripts: NOTE: > Executing update_pixbuf_cache intercept ...
