Well, I try to extend my previous reply (in the meanwhile it crashed again (kernel) with a newly added file). I've got no "unsual" usage of my btrfs partition (is a /home on a logical volume, over a dm-crypted /dev/sda3 partition). The process able to trigger the crash is Azureus. The "unusual" work of it, respect the other programs I run, is its creation of file with lots of hole. When I start to download movies (ehm... iso images of linux distribution...), it does this: first chunk (1~4MB) --- big big big holes (for ~1GB) --- last chunk (1~4MB) then, while downloading, it replaces holes with real data (in a random way, of course). Well, I could try to allocate all space at the time creation. Anyway, today I'll switch to 2.6.27 and new btrfs layout, so I postpone this try after.
