Hi guys!

I have changed my kernel from 2.6.7-r14 to 2.6.8-r4. Now When I try to :

> cedega starcraft.exe

Unable to allocate any shared memory. Is SYSV shm supported/broken on your system?

Le game start, but with black screen, the music play, and I can exit the game by alt+x, that's it... I have checked in my kernel and:

│ │ [*] Virtual memory file system support (former shm fs) │ │

This is activated... before changing kernel, starcraft playin fine.. any idea plz ? :)

after installing the 2.6.8-r4 kernel i tried to start Doom3 and encountered this as well...
"Unable to allocate any shared memory. Is SYSV shm supported/broken on your system?"
after getting this message doom attempts to start and cedega crashes

ran a small gui app i wrote with delphi for win, i get the same message
"Unable to allocate any shared memory. Is SYSV shm supported/broken on your system?"
but the app works regardless.

am using cedega-4.0.1, nvidia 6111 on amd64

also in my kernel:
[*] Virtual memory file system support (former shm fs)

the only other issue i had after installing the kernel was HPET related, but i dont see how it could be related to this

Yes, this seems to be a fairly general problem with 2.6.8-r4. No idea what causes it but it stops Cedega working a lot of the time. Any suggestions would be welcome :-)

(I've tried googling for suggestions, but mounting /dev/shm as tmpfs doesn't seem to make a difference)

Have any of you guys tried 2.6.8-r3? If that works for you then it looks like this is the same problem people are having here:
https://forums.gentoo.org/viewtopic.php?t=221084
and it's due to the x86_64.org patches that got added in -r4.

I was having problems with Cedega too -- turns out it IS specific to gentoo-dev-sources-2.6.8-r4 like herbie had suggested days ago. I finally broke down and down-graded to gentoo-dev-sources-2.6.8-r3 and my problems went away. I highly recommend anyone posting with these problems try this as a solution.

I have filed a bug on this issue -- I searched and was surpised to not find one there already (doesn't mean there isn't one just that I couldn't locate it.)
