| |
| − | * Release tag v4.5 contains a change that broke ''stmmac'' networking on quite a few sunxi devices. The symptoms are
| |
| − | <pre>[ 13.196778] libphy: PHY stmmac-0:ffffffff not found
| |
| − | [ 13.204800] eth0: Could not attach to PHY
| |
| − | [ 13.204809] stmmac_open: Cannot attach to PHY (error: -19)</pre>}}
| |
| − | A quick fix is to revert commit '''88f8b1b''' which introduced the regression. See http://lists.infradead.org/pipermail/linux-arm-kernel/2016-March/415939.html, https://www.mail-archive.com/[email protected]/msg104119.html, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=823493.<br> | |
| − | Version ''v4.5-rc7'' is known to be still okay, ''v4.6-rc2'' fixes stmmac again.
