Can you try backing out this patch (it caused me similar problems on 59, but seemed fine in 62). I suspect it's just changing timing enough that we hit some other bug ... if you could, would be nice to try the ALT+SYSRQ stuff, or turn on NMI watchdogs and get a backtrace ... I've not been able to reproduce this on recent kernels.
