[opensuse-kernel] debugfs mounted by default - necessary?
by Marcus Meissner 06 Dec '11

Hi, is it necessary that "debugfs" is mounted by default? It exposes too much of the kernel readable (and so potentially exploitable) to the non-root user.

[opensuse-kernel] Thinkpad T61p with 12.1
by Hans-Peter Jansen 06 Dec '11

06 Dec '11

Hi, not sure, if this is the adequate forum for my issues, but before filing bugzillas, I try to figure out the correct tree to bark at... My Lenovo Thinkpad does not switch off on shutdown, it reboots properly, the shutdown sequence runs fine too, but it simply doesn't switch off finally. I tried switching from "auto" to "poweroff" in /etc/sysconfig/shutdown, but no change. Next, my desktop claims, that hibernation was disabled by administrator, but this is not correct. Correct is, that I'm unable to enable it.. An attempt to manually hibernate the system nearly succeeded, only the display kept black (maybe related to nvidia drivers). The notebook has a longer history of installations, starting with 11.1, but I tried hard to keep it tidy (no tarball compile, etc..). 11.4 was able to switch it of, but failed hibernation wise. The system is the 15.4' nvidia based one, with prop. nvidia drivers: See: http://www.thinkwiki.org/wiki/Category:T61p It smells, like these issues are ACPI related. Any takers?

[opensuse-kernel] posix_fadvise and tmpfs
by Cristian Rodríguez 05 Dec '11

Hi: calling posix_fadvise with advice POSIX_FADV_WILLNEED on a tmpfs filesystem returns EINVAL.. I know that it will have no effect since stuff written there is already in the page cache, but shouldn't it return 0 acting like a no-op instead ? whom to blame here the kernel, libc , posix ? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Sound suddenly disappeared
by Ilya Chernykh 03 Dec '11

I run openSUSE 11.4. The system worked well for two years since 11.2. I did not change anything in the settings, just usual system updates. I have the sound disappeared from the system. After boot there is no sound at all If to restart the sound system via Yast, the sound appears in one application, but after closing that app there is again no sound at all, in any application, including the same. I tried this with Mplayer, Kaffeine, Hydrogen, Savage 2. Even copying /dev/random to /dev/dsp does not work. lsoff does not indicate any sound devices to be occupied. I have standard Asus P5B motherboard with Intel HDA sound. Once I received a messagebox "error loading sound drived" but did not receve such messages again. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org
