Package: linux-image-3.2.0-1-mckinley Version: 3.2.4-1 Severity: important As reported first in http://lists.debian.org/debian-ia64/2012/01/msg00016.html, I'm getting stability issues with kernel > 2.6.38.
I've bisected the problem to commit 37a9d912b24f96a0591773e6e6c3642991ae5a70 (futex: Sanitize cmpxchg_futex_value_locked API). Here are some issues that can be easily observed: - in a X session (tested under GNOME Classic as well as TWM), hitting the Tab key while in a terminal window instantly triggers a X restart. X isn't crashed as I wrongly assume initially. From the logs, it's definitely properly shut down and restarted - still in a X session, clicking on the "Edit" menu or "Back button" of Firefox/Iceweasel triggers a crash of Firefox/Iceweasel. For this scenario, I have some kind of gdb stack trace in PulseAudio, before gdb itself goes wrong (more on this later; core file available) First investigations let me wrongly assume that these issues were related to something bad in PulseAudio, as uninstalling PulseAudio fixed both of them (Tab key in a terminal issue and Firefox/Iceweasel crash). However, other crashes make me believe that PulseAudio was only a evidence of something more general broken since the bisected commit. Most notably, gdb can't be started at all. Every attempts to debug a program immediately ends up with a SIGTRAP signal. Quite problematic to debug further... It's noteworthy that the exact same system doesn't exhibit these issues when rebooted with kernel linux-image-2.6.38-2-mckinley. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing') Architecture: ia64 Kernel: Linux 3.2.4-1-mckinley (SMP w/2 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
