Sad. Nothing in /sys/kernel/debug, I tried turning on some config
options at random before doing this run (including lockdep), but I
still don't have these. Guess it's time to read some docs :)

I felt a little bothered by this issue, so I dug in a little further.
I basically created a sample mysql, tar, and it seemed that having
memory pressure helped, so I created an allocator as well.

The "mysql" program basically just has 10 threads, each with their own
O_DIRECT-opened fd, reading/writing to random locations in a large
file.

The "tar" program opens the file, reads it in sequentially with plain read().

The "malloc" program allocates a configured amount of memory in the
system and then exits. Ideally this should be the amount of RAM in the
system.

I ran all this in a VM (kvm) with 4 VCPUs (the machine itself is 4S,
8C/S), 512M ram, 512M swap, and a dedicated lvm-backed volume for the
test XFS partition (3G). The warnings were no problem to trigger,
coming off at around one per second on average, the hang took about
4-5h to appear [although in the previous 8+ hour run, nothing
happened, and then I added lockdep].

Basically I was running in three separate shells:

./test-mysqld /mnt/tmp/test
./test-tar /mnt/tmp/test
while true; do ./test-malloc; done

(oh, and /mnt/tmp/test is a 3G file on a newish XFS; the fs was
created/used in prior boots as well, so not completely brand new)

test-tar ended up eventually stuck in a D state, as well as one of the
mysql threads. I could still create/delete files on the filesystem
(although I didn't try writing anything substantial).

The system is still up and running in this state, let me know if you'd
like me to try doing something in particular to it.

Below I have the program source code, as well as output from echo t >
/proc/sysrq-trigger.

The programs [this is not the cleanest code I've written, but it
apparently does the trick... probably left over unnecessary stuff from
earlier debugging in there]:
