Hi,

since some kernels releases (I didn't test thorougly but at least 4.16
and 4.17) I have regular freezes in certain situations on my laptop.

It seems to happen when I:

- tether using my iPhone (involving ipheth)
- mount an IPsec tunnel over IPv4
- run evolution to fetch my mail (IMAP traffic over IPv6 inside the IPv4
  IPsec tunnel)

When I do that, the interface seems to freeze. Last time the mouse was
still moving so the kernel didn't completely crash, but the UI was
completely irresponsive. I managed to get the attached log from
/sys/fs/pstore with refcount_t stuff pointing to an underflow.

Since this doesn't happen if all three conditions aren't met, I've added
a lot of people to the CC: list, sorry for the noise.

I can try to add debugging here and there if needed, but any pointer to
where would be helpful. I'm especially puzzled about the presence of
net/unix/af_unix.c:491 unix_sock_destructor+0x97/0xc0 in the log.

Regards,
-- 
Yves-Alexis
