But still out of ideas. The VPN used to work for years and still works under the old kernel. -- You are receiving this mail because: You are on the CC list for the bug.

This might be related to [1] and there's a fix[2] for it already.
Could you please try TEST kernel package[3] with the fix backported?
Thanks.
