Yeah, but I am not ready to give xfs another change yet. The nasty bugs back in 2.6.8ish days still hurt. Locking up the filesystem when doing rm -rf gcc-4.0 and having to repair it after a reboot was not fun. > MythTV calls fsync every few seconds on ongoing recordings to prevent > stalls due to large cache writebacks on ext3. Yeah. What I have been seeing since 2.6.24 or 2.6.25 or so is that it sometimes simply doesn't start playback on a file, and after 15 seconds or so times out, and then you ask it to try again and it works the next time just fine. Then at times it will stop responding to the keyboard or remote in mythtv for up to 2 minutes, and then suddenly it will respond to whatever you hit 2 minutes ago. Fortunately that doesn't seem to happen that often. I was hoping to see if 2.6.28 helped that, but lirc didn't seem to work on my remote with that version, so I went back to 2.6.26 again. I haven't tried 2.6.29 on it yet since I am currently trying to fix the debian nvidia-driver build against the new kbuild only much too clever linux-headers-2.6.29 package they have come up with. I think I have got that figured out though so I should be able to upgrade that now. -- Len Sorensen -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
