I agree. Seems strange but... I'm actually wondering if the hang and crash is a buffer overrun. I looked on a newly rebuilt system and saw the corruption but it was only a few lines long and the system still worked. I've got a pile of development systems are updated every time a kernel gets updated (once or twice a week) that that line had hit over 800K long. They're all largely mirrors of each other, just with different tasks. Each of the "corrupt" files were identical but all of the updates have been in lock step. All but one of the six affected systems are back up and the single one that's not managed to boot the kernel and started but ran into a panic. But I get a kernel menu on it now. Just checked my x86_64 system (a Lenovo Yoga 730-15). No sign of the corruption in that file. Very strange but 6 systems impacted at nearly the same time (hours). Mike -- Michael H.
