I tried the 39-rc4-wl (wireless-testing) kernel that was based off of 39-rc4, and I see hard-drive read errors there, and eventually crashes. I didn't try Linus's 39-rc4. Yesterday's rc4+ kernel ran fine overnight. I had previously bisected this to a merge in post 2.6.38 code, but I never found time to figure out what part of the merge was funky. In general, from 2.6.38 to very recently, the kernels have been very unstable on my systems, with multiple networking crashes and this block level and/or hard-drive stuff causing trouble, so it's hard to tell exactly when certain bugs were introduced. 2.6.38 has been stable, as has 2.6.38-wl. If there is some other specific commit you'd like me to test I can do so.
