Hello,

I'm currently developing some applications with explicit threading using forkIO and have strange behaviour on my freshly installed Ubuntu Karmic 9.10 (Kernel 2.6.31-14 SMP).

Setup: Machine A: Quadcore, Ubuntu 9.04, Kernel 2.6.28-13 SMP Machine B: AMD Opteron 875, 8 cores, 2.6.18-164 SMP- (some redhat) Machine C: Dual-Core, Ubuntu 9.10, Kernel 2.6.31-14 SMP Compiler on all machines: ghc 6.10.4 (downloaded from GHCs official website)

Hi, I have a dual-core Ubuntu 9.10 machine (running whatever GHC comes with the distro -- 6.10.x), so if you put your test code somewhere that I can get at, I can run it and see if I get the same effect. Thanks, Neil.
