Tuxonice 2.6.27 Patch
Download Fedora/RHEL kernels with enabled Software Suspend 2/TuxOnIceOn this page I provide kernels for Fedora Core with Software Suspend 2 intregrated. All kernels arecompiled for i686-UP and Core 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20. There isalso a version for Redhat Enterprise Linux 5. Starting with Fedora 9 many kernels are also providedin a PAE version. For newer releases also 64-bit builds are provided.These kernels include the same features as the distribution kernels and can used directly withoutlosing any functionality. Some kernels may not work but are provided here for testing and debuggingpurposes. Please see the comments for which kernel to use.
September 23, 2009This article was contributed by. Editor's note: Greg Kroah-Hartman has graciously agreed to write anoccasional column for LWN in which he answers questions that readers maywish to ask of the kernel development community. Greg will do a great job,but the key to a successful column will be good questions; please come upwith your best and send them in.Hi, and welcome to a new semi-weekly column.
Ipc Tm 650 2.6.27
BackgroundI have been living with very visible kernel issues on my machine for about2.5 years:. resume doesn't work if I use the open source nvidia driver.
Work-around:use the nvidia proprietary one. my mouse doesn't work after I come back from suspend: workaround unbindthen bind my i8042 driver. I get very very poor overall machine performance when using sdcards (Ican't use my machine for about 2 minutes): workaround avoid using sdcardswhen one expects to use the machine afterwards.
etcSo why don't I get those issues really fixed?I usualy run a distribution kernel om my machine. I've compiled my ownkernels in the past, althought not in the past years.
I've posted severaltimes on lkml but I almost never got the issues fixed as a result. Theproblems were maybe harder to describe than the ones above though.I now often use launchpad to report my issues. In lkml I often feel that mybugs are lost in the middle of a sea of other bugs. I feel that thecommunication throughput with the kernel developers isn't big enough.Another issue is that upgrading the kernel is not always possible as itrequires to update userspace.I am willing to invest time to get those issues fixed yet I have to getsome confidence that the time I am going to invest is going to be usefull.It's sometimes hard when the machine is used as a work-machine. Rebootingmeans losing 10-15 min in context switching and lost revenue.Question: How do I open an effective communication channel with a kerneldeveloper to get my issues fixed? There surely is with tuxonice, which does a full ACPI S5 powerdown after hibernating.
Suspend-to-RAM and lower suspend states are always iffier than full suspend-to-disk precisely because they don't turn the whole box off and let it reinitialize itself conventionally.(I may have messed up terminology here: I can never remember which of 'suspend' and 'hibernate' is to disk and which to RAM. I've been talking about suspend-to-disk at all times, mainly because I've never managed to get suspending to RAM working with anything Linux-like.or. Windows-like. The last time I owned a machine.that. worked on was so long ago that it was running DOS.). Here's another data point for you: I suspend-to-RAM my Thinkpad about four or five times a day and it works perfectly. Well, almost, the exception is the iwl3945 driver which crashes hard after a number of cycles (actually it's enough to 'ifconfig wlan0 down' and then 'up' a number of times) which means when the link state is wrong it's time to reboot (it's a distribution kernel and not mainline).

Anyway, some hardware works better than others and that may be a good thing to keep in mind when shopping for hardware. I'm laughing!
I have observed the same problem once or twice (also more irritatingly, a symptom similar to the old bug of not aging networks whilst suspended so my machine tries to hook up with the work network when I open it at home and vice versa).I find rmmod works, though IIRC is not guaranteed to. So I happily rmmod iwlagn && insmod iwlagn and wireless lives indefinitely.The only thing that crashes on me after extended use now is Firefox with its many tabs and sandboxed proprietary Flash player. Yet it all comes back in more-or-less the same state when I restart it, thanks to sqlite. Crash-only software rules, ok!
