Hi, I have done some tests and these are the results: * net.git (133800d1f028): probe failed * net.git (133800d1f028) + revert: everything fine * net.git (133800d1f028) + revert + "stmmac: fix MDIO settings": everything fine * today's linux-next: probe failed * today's linux-next + revert of 88f8b1bb41c6 stmmac: Fix 'eth0: No PHY found' regression: probe succeeded but no network at all * today's linux-next + revert of 88f8b1bb41c6 (stmmac: Fix 'eth0: No PHY found' regression) + revert of 0e80bdc9a72d (stmmac: first frame prep at the end of xmit routine): probe succeeded, dhcp succeeds and nfsroot works for a few seconds before timing out Btw, could you CC LKML on future patches that need testing?
