But now it doesn't matter if Cardbus/PCMCIA is compiled in or not. What also matters is a setting in the BIOS: If i set instead of Power -> SpeedStep -> Mode for AC - "Max Performance" Mode for Battery "Max Battery" to Power -> SpeedStep -> Mode for AC - "Max Battery" Mode for Battery "Max Performance" he _does_ boot from battery but also on AC... Also the problem is now(?) not very reliable. Sometimes the boot is successful even on battery and then the laptop works without a glitch. This makes it not easier to isolate the problem. About the reverts of some patches: I'm not, lets say it carefull, an very experienced git user;-) What i get is: # git-revert -n cf4c6a2f27f5db810b69dcb1da7f194489e8ff88 First trying simple merge strategy to revert. Simple revert fails; trying Automatic revert. Auto-merging arch/i386/kernel/io_apic.c merge: warning: conflicts during merge ERROR: Merge conflict in arch/i386/kernel/io_apic.c .... Is somewhere a howto-revert-patches-in-kernel-git-for-raw-beginners? <earny>
