Bug#762306: lockup when accessing cifs-mounted file on 3.17.0-rc1 and later when remote samba server is restarted
I was trying to reproduce this with totem playing a 30 second FLAC file over the network mount but wasn't able to - how did you repro it?

Hi, I just did: aplay file-on-server.wav where the file was several minutes long and I could repeatedly restart the samba server if I wanted to, but if I had a crash it happened on the first restart of the server. WAV files have the advantage in testing of a constant and fairly high data rate for playback. Regards, Arthur.

Retried (slightly earlier build) but instead of doing ifconfig lo down I did a killall of smbd - I then got a system hang within a few seconds of killing samba.

Bug#762306: lockup when accessing cifs-mounted file on 3.17.0-rc1 and later when remote samba server is restarted
Sorry, I only tried doing a service restart rather than a service stop, wait, service start. I assumed the problem happened when the client was starved for input when smbd was stopped. I notice that the patches for this have come through to Linus' tree. I am rebuilding the kernel with them after removing Pavel's test patch. Regards, Arthur.

Subject: [PATCH] CIFS: Fix readpages retrying on reconnects
If we got a reconnect error from async readv we re-add pages back
to page_list and continue loop. That is wrong because these pages
have been already added to the pagecache but page_list has pages that
have not been added to the pagecache yet. This ends up with a general
protection fault in put_pages after readpages. Fix it by not retrying
the read of these pages and falling back to readpage instead.

Bug#762306: lockup when accessing cifs-mounted file on 3.17.0-rc1 and later when remote samba server is restarted
I also reproduced the general protection fault with the current Linus git head (3.17-rc6+) and trying each of vers=1.0 and vers=2.0 and vers=3.0.
