Subject: net: smsc95xx: aligment issues
Hi,
after connecting a Raspberry Pi 1 B to my local network i'm seeing aligment issues under /proc/cpu/alignment:
User: 0
System: 142 (_decode_session4+0x12c/0x3c8)
Skipped: 0
Half: 0
Word: 0
DWord: 127
Multi: 15
User faults: 2 (fixup)
I've also seen outputs with _csum_ipv6_magic.
Kernel config: bcm2835_defconfig
Reproducible kernel trees: current linux-next, 4.17-rc2 and 4.14.37 (i didn't test older versions)
Please tell if you need more information to narrow down this issue.
Best regards
Stefan
