you're thinking of sis(4) for the short cable problem. there was a problem with VT6105M with vr(4) fixed 2009/04/28 where some link-state changes caused the nic to wedge. there was also a problem with the MCLGETI code (added on 2009/06/18) where high packet rates (or possibly a busy machine) caused the nic to wedge. a fix for this was committed recently (2011/01/13). if people are still seeing problems with vr(4) wedging on a 4.9-beta kernel they should write up a report with as much detail as possible and submit it as a PR with sendbug(1).
