Comment (by ivaradi):
I applied the patch to CC and have tested it for 4 days with heavy
traffic. So far the softirq storm has not appeared (and neither was the
TX_STATUS_PS getting stuck phenomenon detected). So I think the patch
solves this issue.
What I detected though was the DHCPv4 problem described above and eth0
(the LAN ports) getting stuck completely (i.e. no traffic at all, though
wifi and the WAN port continued to work properly). They can both be
resolved by resetting the interface with ifconfig up/down. They also
appeared earlier as well, so they are not caused by the patch and are
probably unrelated to this issue.
I guess the issue of eth0 getting completely stuck might be a case of DMA
getting stuck not detected by the current check. Do you think this could
be the case, i.e. is it worth trying to debug with this assumption?
The DHCPv4 problem is quite baffling as other traffic seems to be
unaffected, and it also appears quite rarely...
