Re-hello, I have tested this AMILO Li1718 laptop with Ubuntu 12.04 and two new upstream kernels. This laptop kept crashing no matter what kernel I booted with, BUT IT WORKED VERY WELL after I installed the "fglrx" or "fbdev" video drivers.
Test 1) FAILED. I tested Ubuntu 12.04 with these three kernels: vmlinuz-3.2.0-20-generic-pae (standard kernel in Ubuntu 12.04) And two upstream kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc7-precise/ vmlinuz-3.3.0-999-generic vmlinuz-3.3.0-999-generic-pae The video driver was the default "xserver-xorg-video-radeon". The laptop crashed (within half an hour) no matter which kernel I booted with. Please see listing of: dpkg -l | egrep "radeon" http://www.futuredesktop.com/amilo/dpkg.radeon lsmod.redeon http://www.futuredesktop.com/amilo/lsmod.radeon Xorg.0.log http://www.futuredesktop.com/amilo/Xorg.0.log.radeon ----------------- Test 2) SUCCESS. I booted with Ubuntu's standard vmlinuz-3.2.0-20-generic-pae kernel. The kernel did not matter in this test. Then I installed the "fglrx" driver which I suppose replaces the default radeon driver in Ubuntu. [from wikipedia.org: Fglrx is the name of the Linux display driver used for ATI Radeon and ATI FireGL family of video adapters and stands for "FireGL and Radeon for X".] The Laptop runs like a dream. It does not crash anymore. I have tested it with very heavy load and various tasks in several hours and it simply runs and runs. Please see listing of: dpkg -l | egrep "radeon|fglrx" http://www.futuredesktop.com/amilo/dpkg.fglrx lsmod http://www.futuredesktop.com/amilo/lsmod.fglrx Xorg.0.log http://www.futuredesktop.com/amilo/Xorg.0.log.fglrx ------------------- Test 3) SUCCESS. I booted with Ubuntu's standard vmlinuz-3.2.0-20-generic-pae kernel. Then I copied /etc/X11/xorg.conf.failsafe to /etc/X11/xorg.conf and rebooted. This xorg.conf uses "fbdev" as video driver. And the laptop runs very well this setting. I cannot make it crash. Please see: xorg.conf http://www.futuredesktop.com/amilo/xorg.conf dpkg -l | egrep "radeon|fglrx" http://www.futuredesktop.com/amilo/dpkg.fbdev lsmod http://www.futuredesktop.com/amilo/lsmod.fbdev Xorg.0.log http://www.futuredesktop.com/amilo/Xorg.0.log.fbdev ------------------- This laptop has AMD/ATI Radeon Xpress 200M graphics chipset. $ lspci -v | grep -i vga 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RC410 [Radeon Xpress 200M] (prog-if 00 [VGA controller]) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/744777 Title: Kernel Oops - BUG: unable to handle kernel paging request at 3f93cd3a; EIP is at kfree+0x3d/0xe0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/744777/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
