I encountered similar problem on Lenovo T420s. I got the flash disk partition renamed from /dev/sdb1 to /dev/sdc1 after several suspend/hibernate/suspend to both/resume cycles that rendered my live system unusable (due to rename). Thus it seems not to be 100% reproducible on my system. I had the flash disk connected to yellow charging USB port, but I am not sure whether it is the real source of the problem (I will retry to reproduce this with regular USB port).

This is USB doing device re-enumeration. There really isn't anything that can be done here. We'd suggest you use UUIDs or labels for devices instead of raw device nodes. |
