Hi Pavel,
Hi Steven!
I've only slightly followed wine-devel recently
Are you using a stock Fedora kernel?
No. I'm using vanilla kernels just with exec-shield patch from Ingo Molnar. I'm not using any well-known distro.
They are all (x86-64) built with SMP support.
My ones are also built with SMP support, because both the 64bit machines have dual-core CPUs. One of them is Pentium-D and the second is Dual Opteron.
Would it be possible to check with a custom built non-smp kernel to see if you have the same behavior?
OK. These machines build a kernel in 3 minutes, no problem to try to disable SMP and verify. However, the 32bit one is also SMP :-); it's MSI K7D Master board populated with 2 Athlons MP. It works perfectly and it's ideal for gaming, because one CPU handles Xserver and similar and the other runs the game :-). wine has no problems with it.
I've been looking in to this matter myself but its been slow going because I lack a 64bit system here. Can you run a strace on a winelib process and send us the results with both the SMP and non-smp kernels?
Will do. With regards, Pavel Troller
