BUG: kernel panic after jbd bugs / kernel paging request

[kardan <kardan@riseup.net>]

[-- Attachment #1.1: Type: text/plain, Size: 5230 bytes --]

Dear developers,

At first thanks for all your work!

kernel version: 3.9.9-t23
kernel config: https://paste.debian.net/27351/
lspci -nvv output is attached.

I merged two kernel issues into one mail to find relations easier.

As both appeared only once I did not invest more time to try with
newer kernels. But I will do so for testing patches. Please give me
pointers where to dig in for reproducing.

1) jbd2_journal_dirty_metadata

I reported this in #linuxfs and was confirmed to forward it here.

12:55 < kardan:#linuxfs> it seems like my hdd is hanging (hdd led
turned. jbd is buzy for over an hour now:
1326 be/3 root          0.00 B     16.00 K  0.00 % 98.47 % [jbd2/sda1-8]

The load was caused by iceape (or something stacked below)
#1  0xb764680e in wait4 () at ../sysdeps/unix/syscall-template.S:81
#2  0xb76467e7 in __wait3 (stat_loc=..., options=0, usage=0x0)
at ../sysdeps/unix/bsd/bsd4.4/wait3.c:3312:55 

This led to several jbd related kernel bugs and a kernel panic in
the end. I attached the jbd-schedulings-bugs to avoid wrapping issues.

This issue dates back some weeks, sorry for not reporting earlear.

I had two occurances of this with several days in between. 
One week before the first occurence a new ram bank and a PCMCIA card
usb hub was added to the laptop.

Some days ago I saw a lot of IO errors once, they did not reappear.
On #linux-fs it was said the first one looks like use-after-free or
some other type of software-induced memory corruption. 

"Those tend to be nasty problems that can take months to track down
some of the crazy-looking problems end up as bad hardware.

have you also experienced crashes of userspace programs?"
kswap/kworker were followed by Xorg, iceweasel, claws and Xorg.

Awesome was inresponsive afterwards and I needed the restart lightdm.
In a new X session parts of old windows reappeared, this was
reproducable.

Log is attached.
