Run JACK and launch xmms with the JACK output plugin. Close XMMS. The xmms process hangs. Strace looks like this: rlrevell@krustophenia:~$ strace -p 7935 Process 7935 attached - interrupt to quit futex(0xb5341bf8, FUTEX_WAIT, 7939, NULL Just like in the above bug report, if xmms is run with LD_ASSUME_KERNEL=2.4.19, it works perfectly. I have reproduced the bug with 2.6.12-rc1.
