Description of problem: Sometimes after getting back from s2disk, I was starting python cli from konsole (KDE). The system completely crashed to a (sorry) "black screen of death"... I wrote down (on a paper... so it is incomplete) some bug logs that I thought will not be in /var/log/messages, but gives something to hang on: BUG: unable to handle kernel NULL pointer at 0000000000000078 IP: [...] raw_spin_lock PGD Oops SMP CPU1 Modules linked:...

Is my computer strange or what ? I got another segfault after cold boot, on starting X11. The console prompt was functional, but X refused to start from there. I tried a "reboot" as Root, the system crashed (could not fully turn off); I had to shut it down manually. Rebooting gave a fully functional system .

This message is a reminder that Mageia 2 is nearing its end of life. Approximately one month from now Mageia will stop maintaining and issuing updates for Mageia 2. At that time this bug will be closed as WONTFIX (EOL) if it remains open with a Mageia 'version' of '2'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Mageia version prior to Mageia 2's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Mageia 2 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Mageia, you are encouraged to click on "Version" and change it against that version of Mageia. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Mageia release includes newer upstream software that fixes bugs or makes them obsolete. -- The Mageia Bugsquad
Mageia 2 changed to end-of-life (EOL) status on ''22 November''. Mageia 2 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Mageia please feel free to click on "Version" change it against that version of Mageia and reopen this bug.
