I built all of Qt and the rest of my desktop with no crash. Anyway, the details are: panic: moea_pvo_to_pte: pvo 0x413f5960 pte does not match pte 0x2a33340 in moea_pteg_table (0x87399bbf.0x570a0180, 0x87399bf. 0x570a6012) And, it is fully reproducible for me just by backing up ports and building x11/xorg. - Justin
