With the next reboot after today's System Update (which included updates for pkg's linux and nvidia) the kernel was not able the partitions anymore and froze. Having the system restored with a liveCD and chroot I found in pacman.log dozens of lines like this [2012-06-15 17:39] -> Running build hook: [fsck] [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/at$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ [2012-06-15 17:39] cp: cannot stat '/lib/modules/3.4.2-2-ARCH/kernel/drivers/hi$ Because no one else reported this here it seems to be specific to my installation. Did the modules move to another directory with 3.4.2-2 oder did I miss a package in the past ? Best regards, Nelson. P.S.: In pacman.conf I have the packages 'linux' and 'nvidia' to the 'IgnorePkgs' line but this shouldn't be the last clue I guess.
