Package: kernel-2.6.18 Version: linux-source-2.6.18 Severity: normal
As soon as I started to do some work on my new Debian Etch system, I got several severe lockups per day. "Severe" means: Ctrl-Alt-Del has no effect, and Alt-Print s does not sync the filesystem. The lockups happen, if I switch from X to a tty, or from a tty to X. They don't happen every time, but with a chance of 1:20 - 1:50, about 5 or 10 times a day. (Thank God or somebody else for ext3...) The problem does not exist under Debian Sarge on the same computer. Or sort of: If switching from a certain X program (gthumb) to tty, there is sometimes a slight corruption under Sarge, which can be cleared easily by switching back, changing to a different Gnome workplace, and switching to tty again. Additional system information: 1) Framebuffer The Framebuffer is installed with the following Grub line: kernel /boot/vmlinuz-2.6.18 root=/dev/sda1 ro video=matroxfb:vesa:0x1B5,fh:85000,fv:110 (I calculated the line, when I installed the Matrox card under Debian Woody, many years ago.) It reports itself as Boot video device is 0000:01:00.0 <...> matroxfb: MTRR's turned on matroxfb: 800x600x24bpp (virtual: 832x6721) matroxfb: framebuffer at 0xCE000000, mapped to 0xdc880000, size 33554432 Console: switching to colour frame buffer device 100x37 fb0: MATROX frame buffer device matroxfb_crtc2: secondary head of fb0 was registered as fb1 <...> Linux agpgart interface v0.101 (c) Dave Jones agpgart: Detected an Intel 440BX Chipset. agpgart: AGP aperture is 256M @ 0xd0000000 <...> Matrox MGA G200/G400/G450/G550 YUV Video interface v2.01 (c) Aaron Holtzman & A'rpi mga_vid: Found MGA G400/G450 at 0000:01:00.0 mga_vid: MMIO at 0xde9a0000 framebuffer: 0xCE000000 mga_vid: OPTION word: 0x50044120 mem: 0x10 SGRAM mga_vid: detected RAMSIZE is 32 MB mga_vid: 1 supported cards found mga_vid: using major: 83 (assigned or default!) <...> [drm] Initialized drm 1.0.1 20051102 [drm] Initialized mga 3.2.1 20051102 on minor 0 agpgart: Found an AGP 1.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 1x mode [drm] Initialized card for AGP DMA. 2) X My EIZO/Nanao CRT is a little older, and does not report its capabilities back to the video adapter. I install it in /etc/X11/xorg.conf with Mode "1152x864" DotClock 127.83 HTimings 1152 1176 1304 1504 VTimings 864 868 872 902 EndMode (I calculated the line, when I installed the Matrox card under Debian Woody.) Additional information: Kernel with video drivers and mga_vid module are compiled from stock Debian Etch Stable. Since my settings have worked well under Debian Woody and Debian Sarge, since quite some years, I assume a video driver problem.
