kernel2.6.x - 間違いだらけの備忘録

2.6.18-rc3をVMware5.5.1上のSargeで動かした時の問題

RAMDISK: cramfs filesystem found at block 0
RAMDISK: image too big!(41624KiB/16384KiB)
VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

grubでの起動時にオプションを追加し、RAMDISKのサイズを拡大、しかし

RAMDISK: cramfs filesystem found at block 0
RAMDISK: Loading 41624KiB [1 disk] into ram disk... done
No filesystem could mount root,tried: ext2 iso9660
VFS: Cannot open root device "sda1" or unknown-block(0,0)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

手詰まり

別VMware環境から持ってきたKernelimageを使用してみる。

umount: devfs: not mounted
pivot_root:No such file or directory
/sbin/init: 432: cannot open dev/console: No such file
Kernel panic - not syncing: Attempted to kill init!

そのカーネルイメージからconfigを流用してみる

modprobe: FATAL: Could not load /lib/modules/2.6.18-rc3y/modules.dep: No such file or directory
modprobe: FATAL: Could not load /lib/modules/2.6.18-rc3y/modules.dep: No such file or directory
umont: devfs: not mounted
pivot_root:No such file or directory
/sbin/init: 432: cannot open dev/console: No such file
Kernel panic - not syncing: Attempted to kill init!

initrdを作り直してみる

umount: devfs: not mounted
mount unknown filesystem type 'devfs'
umount: devfs: not mounted
pivot_root:No such file or directory
/sbin/init: 432: cannot open dev/console: No such file
Kernel panic - not syncing: Attempted to kill init!

あまり変わらない

仕方ないので、
vmxファイルを
#scsi0.virtualDev = "lsilogic"
scsi0.virtualDev = "buslogic"
と修正したところ、
kernel2.4用VMで作ったkernel2.6.17-rc3が動作した。

debian吊しのconfig-2.6.8-2-386だと、
