The partition is a physical ~5GB --mixed lzo compressed partition. The kernel 2.6.39-rc1 + reverted commit c59021f846881a957ac5afe456d0f59d6a517b61. (see http://www.mail-archive.com/[email protected]/msg09083.html)
This time I've really filled whole partition and kernel OOpsed. Note, the blow came right after INFO about hung write task (see full dmesg), so it could be bad guy.
