Fixed by commit 494de90098784b8e2797598cefdd34188884ec2e: "Do not overwrite nr_zones on !NUMA when initialising zlcache_ptr" by Mel. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=10919 > Subject : [regression] display dimming is slow and laggy - Acer > Travelmate 661lci > Submitter : Maximilian Engelhardt <[EMAIL PROTECTED]> > Date : 2008-06-14 22:31 (23 days old) > References : http://marc.info/?l=linux-kernel&m=121348428828320&w=4 I wonder if this one could be related. The 'nr_zones' overwriting bug would result in kswapd not reclaiming any memory asynchronously, so the kernel would basically be constantly under a low-memory situation, and processes would be forced to do synchronous reclaim. That, in turn, could easily explain laggy operation, especially if it is something bigger that needs to allocate new memory (not that I know if X dimming needs to, but I could imagine that it does some double buffering or whatever). > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=10872 > Subject : x86_64 boot hang when CONFIG_NUMA=n > Submitter : Randy Dunlap <[EMAIL PROTECTED]> > Date : 2008-06-05 21:50 (32 days old) > References : http://marc.info/?l=linux-kernel&m=121270308607116&w=4 > http://lkml.org/lkml/2008/6/11/355 > http://lkml.org/lkml/2008/6/15/117 > Handled-By : Yinghai Lu <[EMAIL PROTECTED]> This really doesn't sound like low memory, but the CONFIG_NUMA thing is intriguing, since again, the 'nr_zones' thing depended on that. It would break 'balance_pgdat()' entirely, and maybe some balancing operation can get confused even before you actually run out of memory Unlikely, but worth re-testing. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=11008 > Subject : after laptop re-dock: usb-storage device no longer > detected > Submitter : Lukas Hejtmanek <[EMAIL PROTECTED]> > Date : 2008-06-26 17:37 (11 days old) > References : http://lkml.org/lkml/2008/6/26/391 > Handled-By : Alan Stern <[EMAIL PROTECTED]> > Patch : http://lkml.org/lkml/2008/6/30/305 This patch got merged: commit 1236edf1c70107a0d31b3fba0b2a8783615d0d24 ("USB: don't lose disconnections during suspend"). > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=11006 > Subject : 2.6.26-rc6: pcmcia stopped working > Submitter : Pavel Machek <[EMAIL PROTECTED]> > Date : 2008-06-22 22:40 (15 days old) > References : http://marc.info/?l=linux-kernel&m=121420740806363&w=4 > http://marc.info/?t=121439185700001&r=1&w=4 > Handled-By : Tejun Heo <[EMAIL PROTECTED]> > Bartlomiej Zolnierkiewicz <[EMAIL PROTECTED]> > Patch : http://marc.info/?l=linux-kernel&m=121526230022719&w=4 Ditto: commit 7cd95f56cb61f5348d062527c9d3653196f6e629 ("ide: fix hwif->gendev refcounting") > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=10860 > Subject : total system freeze at boot with 2.6.26-rc > Submitter : Christian Casteyde <[EMAIL PROTECTED]> > Date : 2008-06-05 12:38 (32 days old) > Handled-By : Tejun Heo <[EMAIL PROTECTED]> > Patch : http://bugzilla.kernel.org/attachment.cgi?id=16556 Fixed in commit 70a3143af87c6ca188107cbd49ab5eec2c86c456 ("sata_uli: hardreset is broken") > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=10815 > Subject : 2.6.26-rc4: RIP find_pid_ns+0x6b/0xa0 > Submitter : Alexey Dobriyan <[EMAIL PROTECTED]> > Date : 2008-05-27 09:23 (41 days old) > References : http://lkml.org/lkml/2008/5/27/9 > http://lkml.org/lkml/2008/6/14/87 > Handled-By : Oleg Nesterov <[EMAIL PROTECTED]> > Linus Torvalds <[EMAIL PROTECTED]> > Paul E.

Paul? I suspect SRCU will need to be simply marked BROKEN for now, because nobody knows what the problem Alexey sees is. Apparently it's been seen by a few other people too. > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=10726 > Subject : x86-64 NODES_SHIFT compile failure. > Submitter : Dave Jones <[EMAIL PROTECTED]> > Date : 2008-05-16 12:54 (52 days old) > References : http://lkml.org/lkml/2008/5/16/312 > Handled-By : Mike Travis <[EMAIL PROTECTED]> > Patch : http://lkml.org/lkml/2008/5/16/343 Fixed in commit efac41894df57d32b483ac622d03541b5b2692c0 ("x86: fix NODES_SHIFT Kconfig range"). > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=10725 > Subject : USB Mass storage mount fails: Write protect on > Submitter : Maciej Rutecki <[EMAIL PROTECTED]> > Date : 2008-05-16 14:55 (52 days old) > References : http://marc.info/?l=linux-kernel&m=121095168003572&w=4 > Handled-By : Alan Stern <[EMAIL PROTECTED]> > Patch : http://marc.info/?l=linux-scsi&m=121433068314568&w=2 Hmm.
