The referenced commit\nused usleep_range inside the PHY access routines, which are sometimes\ncalled from an atomic context. This can lead to a kernel panic in some\nscenarios, such as cable disconnection and reconnection on vPro systems.\n\nSolve this by changing the usleep_range calls back to udelay."
