Flood of messages in dmesg: "mv643xx_eth_port mv643xx_eth_port.0 eth0: failed to linearize skb with tiny unaligned fragment"
Hi.
I have a kurobox pro, which is an armel NAS with a single SATA HD that runs
with 128MB of RAM. It currently run Debian testing with kernel 4.12.13-1
(not vanilla, I suppose).
I don't remember well, but I think that since kernel 4.12 I started seeing
loads of messages like the following in my dmesg:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
