Description Valdis Kletnieks 2011-12-20 18:58:28 UTC

Description of problem:
After installing 2.14.89025, I was seeing lots of weird issues - programs trying to talk to pulseaudio would hang, firefox was wedged and flickering the X cursor between 2 different cursors, some other weird stuff.

Caught this in gdb of /usr/bin/pidgin hung during startup:

(gdb) c
Continuing.
^C
Program received signal SIGINT, Interrupt.

Reverting to 2.14.90-23 and everything started working normally again - pidgin, pulseaudio, firefox, etc.

Am willing to add instrumentation and re-test if somebody tells me what they want tried.

Comment 1 Kazuro Hozono 2011-12-22 00:10:08 UTC

I had similar weird behaviors of applications in F16 (x86_64) after I installed glibc-2.14.90-24.fc16.3. I googled and found (in Bug#651899 in Debian) my problem might be related to glibc-rh552960.patch had been introduced in 2.14.90-24.fc16.x. I locally build glibc-2.14.90-24.fc16.3 without the patch then everything have been working fine for two days. I found the patch has been merged into glibc-2.14.90-25.fc17 tarball. 

Regards,

Kazuro: Thank you for digging further into this, and confirming I'm not crazy (or at least, not hallucinating this particular bug ;)

Comment 3 Valdis Kletnieks 2011-12-29 22:40:34 UTC

Got around to testing 2.14.90-26, which contained this:

  - Revert "fix" to pthread_cond_wait (#769421)

and it does appear to be working correctly on my box again.  Thanks..

Comment 5 Jeff Law 2012-01-02 18:22:28 UTC

Should be fixed by either 2.15-1.fc17 or 2.14.90-26.fc17 (both revert the problematical pthread_cond_wait patch).
