Hello the problem is occured with : - linux kernel 3.4.5 i do not test with 3.4.0 / 1 / 2 / 3 / 4 , but i can if you want - linux kernel 3.5rc6 rc7 / do not test with other rc.
the problem is not occured with : linux kernel 3.3.4 / 3.3.8 These servers are used for : - starting a lot of virtual machine with qemu-kvm ( ~ 40 ) ( lot of select i think) - do a lot of network tests with openvswitch I can test a kernel 3.4.x before and after a commit id (?) to find a regression.
