I have not tried a bisect yet, but I can confirm 4.4 and 4.4.1 work. 4.5-rc1 and 4.5-rc2 don't work. It appears the tx to device times out and then just goes into reset of the device to try and recover. A tx to device seems not to work. although somehow firmware has been loaded to the device. So some types of tx might work. Strange! There were quite a few omap and omap4 plus patches that have come along recently. so the culprit is in there somewhere. These machines have been rock solid for quite some time. If I get time, this evening, I'll see if I can give a bisect a try.
