Well, maybe next time, as I said, now my remote testing server is unreachable. Not that it helps, but my config file originated from Ubuntu 10.10 kernel (2.6.35-generic) and I added some kernel hacking options, like LOCKDEP and friends. I had CONFIG_EXT4_DEBUG and CONFIG_JBD2_DEBUG on. All the rest was just defaults chosen by make oldconfig. If it helps, I can send you a config file from my laptop, which is supposed to be similar to the one on the server (before the changes made my make oldconfig). > > Is this really with 2.6.39-rc7 vanilla kernel (no extra patches!)? > git checkout v2.6.39-rc7 make clean && make Reported kernel version doesn't lie when you're building from GIT and I didn't edit any files manually. > Which xfstest (GIT) version is this? I was using the current (GIT) version, fetched it 2 days ago. I do have some weird problem on my system, which I reported to XFS list a while back and couldn't find a cure: the execution of "umount ; fsck" after the tests sometimes fails to umount (EBUSY) after specific tests. I suspect that this problem in my system is also related to the crash, because test 232 does 2 remounts and that may cause some race on my system. > Which versions of xfs{progs, -libs, dump}? Whatever tools came with the Ubuntu 11.4 upgrade... (cannot check now) I suppose e2fsprogs version is what matters when I am checking ext4 though. > > Here I am on i386 and can help with testing if this helps. > Great! so did you try running xfstests 005 and 232?
