Dear All,

/lib/firmware/microcode.dat
Does anybody know off hand what (how critical) is that, as, if it is related to most famous these days trouble with CPU hardware, I will need to reboot relevant boxes to have new microcode loaded. But if it is not that critical, it can wait till next reboot.

Thanks. Johnny Hughes
