GPF after s2disk since 4.3 (inode_permission+0x1a/0x50)

[Rolf Eike Beer]

Hi all,

I see these backtraces whenever I wake up my laptop from s2disk. This has been 
no problem in 4.2.x. All relevant filesystems I have are ext4. I regularly do 
s2ram and have not seen any problems with that.

Any ideas?

Greetings,

Eike
