I'm running some moderate I/O loads (using 12 devices behind a Smart Array on a 16-way x86_64 box, I'm doing asynchronous direct sequential reads to each disk in parallel), and whilst attempting to get blktrace data I routinely run into this. I first started seeing this in 2.6.29-rc6, so I bumped to 2.6.29-rc7 and made a couple of successful runs, then ran into it again. (I've attached the script I was using, but I'm not sure it's very helpful...) The environment the system under test is in is rather difficult to bisect in, but if need be, I can certainly go through the (painful) motions to do so... I only ran this a couple of times on 2.6.27.7-4 (SLESS 11 b6 kernel), and both times it worked there - not sure how far back the problem occurs... I'm open to any SLAB debug tracing options that may help with this...
