Issue with binfmt_misc with a 64 bit kernel in 32 bit arch

When i try to upgrade nss-mdns pacman hangs at

(1/1) checking for file conflicts                                                  [###############################################] 100%

when i quit i get this

^C
Interrupt signal received
warning: could not get filesystem information for /proc/sys/fs/binfmt_misc: Interrupted system call
(1/1) checking available disk space                                                [###############################################] 100%

Btw i use a 64 linux kernel on arch 32, could be related to that ?

Edit, seems like its related to mixing 64 bit kernel and 32 userspace, qemu hanged too.

Yes, known kernel bug when mixing 64-bit kernel with 32-bit userland.. the autofsv5 packet is broken due to memory misalignment.

Ha, i switched to a 64 kernel when i read the message from Linus today, but i didn't read the followups , thanks

Btw, can this topic be moved somewhere else?, its not pacman related and could be helpful to other users.

Moved to 'kernel and hardware' on OP's request.
