[Solved]NFS, rcpbind, nfs common lockup after latest -Syu

both laptops that i have running arch, same hardware, same -Syu have NFS freezing with 3.4.2-2 update. Anyone else seeing this? when I bang out (!rpcbind !nfs-common) system runs normally. Does anyone have any ideas that i am missing? my server which is on the same -Syu is running without error,

I'm posting this from the server, so i do not have /log/ access to the clients at this time. but i ran a -Syu earlier in the week with with the filesystem upgrade with no isseue,

latest mkinitcpio cleared it up.

Re: [Solved]NFS, rcpbind, nfs common lockup after latest -Syu

I might have the same problem. Just since we have all home directories on NFS4 the problem is pretty severe. It is confirmed on 2 computer already and the latest kernel-update including the use of latest mkinitcpio does not really help. The crash just happen at write access, so far never at read access.

This is the kernel message:

Hope it can be fixed soon - it is a basic Linux function.

@ zero_one: I would appreciate if you could remove the "solved" mark. Thanks!
