Date: Mon, 4 Feb 2008 14:16:15 +0100 From: adi@...omp.erfurt.thur.de (Adrian Knoth) To: netdev@...r.kernel.org Subject: No IPv6 addresses after resume (No buffer space available) 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: adi@...pin:~$ 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.
