Hi!
I use suspend-to-RAM on my HP nx6325 laptop. I have three main
locations:
- place A: IPv4 + IPv6
- place B: IPv4 + IPv6
- place C: IPv4 only
Suspending in place A and travelling to place B is no problem, I'm
always getting the local RAs, the right addresses a.s.o.
But once I've been in place C (no IPv6 there at this site), resuming in
A or B doesn't give me IPv6, I don't even get a link local address. Only
the loopback interface is left functional:
[EMAIL PROTECTED]:~$ ls /proc/sys/net/ipv6/conf/
all default eth1 lo
chopin:/home/adi# ip -6 a s
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
eth0 is missing, also in /proc/sys/net/ipv6/conf (as shown above).
When I try to assign my link local address, it fails:
chopin:/home/adi# ip -6 a a fe80::0217:a4ff:fed7:a23e/64 scope link dev eth0
RTNETLINK answers: No buffer space available
It doesn't help to cycle the interface down and up. My current
workaround is to unload the NIC driver (tg3) and modprobe it again:
[rmmod tg3 ; modprobe tg3]
chopin:/home/adi# ip -6 a s
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
15: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 fe80::217:a4ff:fed7:a23e/64 scope link
valid_lft forever preferred_lft forever
[and a few moments later]
chopin:/home/adi# ip -6 a s
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
15: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:638:906:2:217:a4ff:fed7:a23e/64 scope global dynamic
valid_lft 2591987sec preferred_lft 604787sec
inet6 fe80::217:a4ff:fed7:a23e/64 scope link
valid_lft forever preferred_lft forever
Hope you can identify the culprit.
TIA,
Cheerio
