hrm, i guess this is related to 
 * QA Notice: Package triggers severe warnings which indicate that it
 *            may exhibit random runtime failures.
 * hwinfo.c:1316:27: warning: array subscript is above array bounds [-Warray-bounds]

Only change I can think of was that I added -ggdb and nostrip but some other sw upgrades might have happened too.
