Subject: kernel bug: futex_wait hang
Date: Mon, 21 Mar 2005 22:59:10 -0500 [thread overview]
Message-ID: <1111463950.3058.20.camel@mindpipe> (raw)
Paul Davis and Chris Morgan have been chasing down a problem with
xmms_jack and it really looks like this bug, thought to have been fixed
in 2.6.10, is the culprit.
http://www.uwsg.iu.edu/hypermail/linux/kernel/0409.0/2044.html
(for more info google "futex_wait 2.6 hang")
It's simple to reproduce. 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.
Lee
