Hello,
I'm upgrading a Marvelle Armada 370 board using the mvneta driver from
4.0 to 4.2 and noticed issues with NFS booting.
Basically, most of the time init returns with an error code, or
programs segfault or throw illegal instructions.
Since it worked fine on 4.0 I bisected until I found commit
a84e32894191cfcbffa54180d78d7d4654d56c20 "net: mvneta: fix refilling
for Rx DMA buffers".
If I revert this commit, everything seems to get back to normal.
Could you try it ? The two issues look very similar.
Regards
