bguthroI'm not sure if this is the proper place for this, or not - but I've been working with the intel-gfx list to get a particular Dell laptop working (E6410) - I had posted about this here a week ago or so. The guys over at RedHat found a fix, and applied against the lucid 2.6.32 kernel, it works great for this machine. I think it might be worth cherry-picking into the LTS kernel, for these Ironlake chips12:53
bguthroMy original bug was https://bugs.freedesktop.org/show_bug.cgi?id=28746 - but this was marked as a dup of https://bugs.freedesktop.org/show_bug.cgi?id=2807012:54

mdzI tend to do that often when I'm going to continue using the machine16:42
mdzmy standard command-line upgrade script does it too16:42
mdzsudo ionice -c3 apt-get dist-upgrade16:42
apwyeah i wish i'd done that often with other commands16:42
pgranermdz: cool let me try that as well16:44
smbHm, have not used that much. Don't think it should cause jbd2 to lock so long, though16:44
smbpgraner, You have the proposed kernel?16:44
smbor do you want to try once before and after16:44
mdzapw, it doesn't seem to work as well in 10.04 as it did in earlier releases for some reason16:44
pgranersmb: I'm just trying to get it to repro first16:45
omryhi, I bumped into 571422 with my new laptop. trying to do the workaround suggested in the first comment). how do I get grub2 to accept a boot flag for a kernel?16:45
apwmdz, there are some changes in the stable pipe which may be related ... writeback is borked en-toto as far as i can see16:45
mdzthe idle scheduler used to do a really good job of preserving interactive responsiveness, but in 10.04+ it seems to be less effective16:45
mdzdd if=/dev/zero of=bigfile bs=1M count=1024 makes my system pretty useless whether I run it with ionice -c3 or not16:48
apwsmb, are the writeback patches applied to anything yet?  that mdz could test ?16:51
smbapw, I have a test kernel for the sync issue but that does not include that patch about extending faster that writeback is16:52
apwsmb, perhaps we should shove them both in a test kernel ...seeming this is getting to be a much complained of issue16:53
JFocongrats cnd 16:53
smbapw, Might be possible. Need to check which bug the rest is and see how well the other one applies.16:54

mdzgiven that I haven't been able to reproduce the bug yet?16:59

omryfound some info about that as well, but I need some help in applying the patch and getting the driver to build. (I am not familiar with the ubuntu method of doing this).18:23
