First I've heard of that one (!).

The microcode update is pervasive across the 3560s/3750s.  First time I
ran across it, I was doing a remote IOS update on a number of switches
at a preset maintenance window (reload at xx:yy)... most came right
back, but the ones doing the "microcode update" I thought were a
meltdown and I was packing up for a repair field trip before trying them
one last time before hitting the door...

Very annoying, and very unexpected the first time around...
