The machine seems table with 2.6.36. So I think its really an regression of 2.6.37. I am stuck with what to try next. Since trying to track it down to a specific commit appears too involved for me and its appears also quite laborious to get any value debug information out of the kernel - cause it can take days for the bug to appear -, I am inclined to either test with 2.6.37.1 once its available or just give it a go with 2.6.38-rc3 or rc4. Maybe 2.6.38-rc3/4 would be the best bet, I have seen a report on the btrfs mailing list of 2.6.38 fixing a BTRFS hang bug that appeared with 2.6.37. I am just not sure whether its related or not. Re: [PATCH v2]Btrfs: pwrite blocked when writing from the mmaped buffer of the same page http://marc.info/?l=linux-btrfs&m=129623925116051&w=2 There is another thread about 2.6.37 related BTRFS hang: flush-btrfs-1 hangs when building openwrt http://marc.info/?l=linux-btrfs&m=129594547616298&w=2 I will add this as comment to the bug report as well.
