Package: kernel-image-2.6.7-1-386 Version: 2.6.7-2 Severity: important when booting my laptop (toshiba portege 3020CT) i get a kernel oops almost every time i boot it using AC power, just before it tries to mount the root filesystem. when i boot it from battery power, it seems to work fine. setting acpi=off does not reliably seem to fix the problem, and introduces other problems (pcmcia ethernet card then fails to work). attached is a screen log of a failed boot. live well, vagrant -- System Information: Debian Release: 3.1 APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i586) Kernel: Linux 2.6.7-1-386 Locale: LANG=C, LC_CTYPE=C Versions of packages kernel-image-2.6.7-1-386 depends on: ii coreutils [fileutils] 5.2.1-2 The GNU core utilities ii fileutils 5.2.1-2 The GNU file management utilities ii initrd-tools 0.1.74 tools to create initrd image for p ii module-init-tools 3.1-pre5-6 tools for managing Linux kernel mo -- no debconf information
