Hi,
I have been running two instances of valgrind on some application on 3.10.9 kernel
with a patch aiming to fix a BOS descriptor memleak (see linux-usb Subject
"[RFC v2] usbcore: compare and release one bos descriptor in usb_reset_and_verify_device()"
but I hope it is unrelated). I enabled in the kernel some extra checks for kernel
sanity in Kernel hacking section (am looking for an answer why something overwrites memory
of my python-based application). Hence the valgrind and attempts to fortify kernel a bit
more (see attached diff since last known good .config).

Below I show when I early in the morning connected the external SATA drive drive
and that muich later, kernel suddenly lost ability to read/write the filesystem.
I somewhat suspect that laptop-mode-tools (although configured to ignore mouse/keyboard
and usb-storage devices) somehow triggered the cause. However, still I would like to see
that something happened at the SATA level.

I could imagine valgrind took too much memory and maybe overwrote some kernel structures? Or some of the new changes in .config?

I ran two instances of: valgrind --leak-check=full --track-origins=yes --tool=memcheck --suppressions=valgrind-python.supp my_app_compiled_by_cython_and_gcc [args]

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 573G 533G 12G 98% /
devtmpfs 7.8G 0 7.8G 0% /dev
tmpfs 1.6G 3.0M 1.6G 1% /run
shm 7.8G 0 7.8G 0% /dev/shm
/dev/sdb1 2.7T 1.4T 1.3T 53% /mnt/external
$ ls -la /mnt/external
ls: reading directory /mnt/external: Input/output error
total 0
$

So, the target filesystem on the external disk should not be full.

Any clues what I should look at? Few days ago memtest86+ went fine through all 16GB of RAM (Dell Vostro 3550). I do not know if the PCI/ACPI change is related or not.
Thank you,
Martin
