CentOS5におけるKernel2.6.3x系カーネル使用注意点 †
以下のOptionが有効になっていないとrootディレクトリをmountできず起動時にKernel Panicを起こす。

CentOSデフォルトの.config
# grep SYSFS .config # CONFIG_SYSFS_DEPRECATED_V2 is not set CONFIG_ACPI_SYSFS_POWER=y CONFIG_WIRELESS_EXT_SYSFS=y CONFIG_RTC_INTF_SYSFS=y CONFIG_SYSFS=y
オプションを有効にした.config。"CONFIG_SYSFS_DEPRECATED_V2=y"となる。

Kernel compile †
#make mrproper CLEAN scripts/basic CLEAN scripts/kconfig CLEAN include/config # cp old/.config # make bzImage # make modules # make modules_install # make install
昨今はmake installで以下の作業を自動で行う。
# cat arch/i386/boot/bzImage > /boot/vmlinuz-2.6.20.1 # cp System.map /boot/System.map-2.6.20.1 # cd /boot # mkinitrd initrd-2.6.20.1.img 2.6.20.1 # rm System.map # ln -fs System.map-2.6.20.1 System.map
boot loaderへの組み込み †
lilo †
# cd /etc
# cp -ip lilo.conf lilo.conf.yyyymmddnn
# vi lilo.conf
# /sbin/lilo
Warning: LINEAR is deprecated in favor of LBA32: LINEAR specifies 24-bit
disk addresses below the 1024 cylinder limit; LBA32 specifies 32-bit disk
addresses not subject to cylinder limits on systems with EDD bios extensions;
use LINEAR only if you are aware of its limitations.

Kernel .config生成 †
If you are compiling this driver as included in the Linux kernel
sources, look for the CONFIG_THINKPAD_ACPI Kconfig option.
It is located on the menu path: "Device Drivers" -> "X86 Platform
Specific Device Drivers" -> "ThinkPad ACPI Laptop Extras".
