Package: kernel-source-2.6.8 Version: 2.6.8-5 Severity: important
I'm using the Debian 2.6.8 kernel on a Dell Latitude D600 laptop. With 2.6.8-1, things worked fine. With 2.6.8-5, if at any time I press the button that detects lid close (which should normally generate an ACPI event "button/lid"), the system instantly locks up hard. This is true from the very beginning of the boot up sequence; while the BIOS correctly turns the screen on and off in response to this button while I'm on the Grub menu, if I select the 2.6.8-5 kernel and then, as fast as I can, hit the lid button, the kernel freezes, extremely early in the bootup sequence. Obviously userspace and modules are not relevant, then, since they never get a chance to start/be loaded... (It doesn't matter, though, when I actually hit the button; if I don't touch the button it will boot normally, I can start programs, etc., but even then, as soon as I touch the button the computer instantly stops responding to any input and the screen stops updating and no messages are left in any logs.) I figured it was probably a bug in ACPI, which I originally had enabled, so I first disabled ACPI support for buttons (CONFIG_ACPI_BUTTON), and then disabled ACPI altogether and enabled APM instead (CONFIG_APM=y, CONFIG_APM_CPU_IDLE=y), and in all three configurations the bug manifested in exactly the same way. Attached is my original kernel configuration with ACPI enabled, that worked fine with 2.6.8-1 but not with 2.6.8-5. -- System Information: Debian Release: 3.1 APT prefers testing APT policy: (700, 'testing'), (600, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.4.26 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 Versions of packages kernel-source-2.6.8 depends on: ii binutils 2.14.90.0.7-8 The GNU assembler, linker and bina ii bzip2 1.0.2-1 A high-quality block-sorting file ii coreutils [fileutils] 5.2.1-2 The GNU core utilities -- no debconf information
