I'm getting this line every 10 seconds or so in my /var/log/current: sleeping function called from invalid context at mm/slab.c:1856 After much reading and comparing, this appears to be coming from my NVidia drivers working on kernel 2.6.0. I have updated to the latest nvidia-kernel ebuild. The changelog mentions that the minions.de patch was included in 4368 (I think) but on the 5xxx driver I'm receiving this message. Did the minions.de patch get included in the latest nvidia-kernel? There is one available at http://www.minions.de if not.
Yes, it's there and applied for 2.6 kernels. You can assume it's there unless the changelog says otherwise; if it weren't there, the ebuild wouldn't have compiled for a 2.6 kernel.
Do you get this message from 2.4 kernels with the "nvidia" driver, or from 2.6 kernels using the "nv" driver?
I'm getting this from the 2.6.0 kernel using the "nvidia" driver... hence why I'm confused about the patch being applied.

Yes I'm aware of where you encounter the issue. I'm asking you to test other cases to try removing the issue. Also, what basis do you have for suggesting the minion.de patch has anything to do with this? I'd like to see some links, etc.
The place I got my information was from this discussion: http://www.ussg.iu.edu/hypermail/linux/kernel/0311.3/0372.html Digging a little deeper, it looks like if I disable "sleep inside spinlock" or something to that effect, this error message will go away... I googled with the search of: sleeping function called from invalid context at mm/slab.c:1856 nvidia Someone mentioned that this didn't start happening until after applying the minion.de patch. Whoa, I'm confused. You kernel hackers will definitely know better than me.
"Not really, it just shows the nvidia driver being buggy and using a sleeping gfp allocation mask when it should not." http://www.ussg.iu.edu/hypermail/linux/kernel/0311.3/0485.html

recompiled nvidia-kernel-1.0.5328 when i installed 2.6, and that's when the error messages began. I assume removing that spinlock option in the kernel would get rid of the errors, but there is SERIOUS performance degradation associated with this. i.e. glxgears gives me 17 fps average on my GeForce4
I don't know whether it was fixed in 2.6.1 or not, but I turned off spinlock checking in my config, and from what I can tell, the majority of speed has been restored.
I've also seen this bug and the symptoms that I am seeing appear to be more serious than others are reporting. I have a system that I use for capturing and playback of DVB-T material. Typical scenario is for one process to record an MPEG2 DVB stream to a file. Another process will be reading a different file from the disk, decoding the MPEG2 stream and displaying it using xv on an nVidia NV17 MX440 card. In gentoo-dev-sources-2.6.1-r1 with nvidia-kernel-1.0.5328-r1 I get the following: Debug: sleeping function called from invalid context at mm/slab.c:1856 APIC error on CPU0: 60(60) APIC error on CPU0: 60(60) Debug: sleeping function called from invalid context at mm/slab.c:1856 This can go for about 10-30 minutes until the system becomes unstable and starts having issues with IDE drive access, eventually resulting in a system corrupted so badly it requires a cold boot. The push of a reset button does not fix up the corrupted state that the hard disk is left in, only a powercycle brings the machine back.

Please let me know if there is any further information I can supply to narrow this problem down.
I'm having very similar problems. I've been documenting in the forums here. http://forums.gentoo.org/viewtopic.php?t=127884 I seem to get the messages on focus changes, but not consistently.
I am getting this too after installing the nvidia drivers.
There are new NVidia drivers on NVidia's website that claims to natively support 2.6 kernels: http://www.nvidia.com/object/linux_display_ia32_1.0-5336.html
Have installed the new drivers from Nvidia (no ebuild yet) and they fix this problem...
Marking as LATER so we can resolve when 533* is marked stable
reopening
Much newer versions of nvidia-drivers are now stable. Closing with the proper resolution.
