Re: [Mkdump-devel] mini kernel can't load?

[Itsuro O. <od...@va...>]

松島様、各位

VA Linux 小田です。

しばらく調査の時間がとれず、遅くなってしまいましたが、
不具合の原因が分かりました。

・発生条件
  ミニカーネルを CONFIG_BLK_DEV_INITRD = y で構築、かつ、initrd を使用しない。

・回避策
  initrd を使わない場合は、ミニカーネルを CONFIG_BLK_DEV_INITRD = y で構築しない。
  ( Device Drivers --->
      Block devices --->
        Initial RAM disk (initrd) support  <=== これをセットしない )

・原因詳細
  mkexec で initrd をロードしなかった場合、ブートパラメタの initrd_start には
  値が設定されるけれども initrd_size は0 であるという、矛盾した状態になるのが
  まずかった。
  ミニカーネルの以下のルートで落ちていた。
  start_kernel
    setup_arch
      setup_memory
        reserve_bootmem(INITRD_START, INITRD_SIZE (これが0))
          reserve_bootmem_core
             BUG_ON(!size)
  (補足)カーネル初期化のこの時点では、まだ正式な割り込みハンドラが設定できて
  いないので、ハングしたように見えていたようです。

修正を一応、添付しますが、特に修正を当てなくても、上記の回避方法で十分です。

松島さんからいただいた.config で"Initial RAM disk (initrd) support"だけを
off にして、うまく行くことを確認しました。また、松島さんが、

とおっしゃっていたのも、説明がつきました。mkexec で initrd をロードした
場合は、きちんとした値が渡りますのでOKなわけです。
