[linux] kernel から Disabling IRQ と言われる。

解決策無し。エラーのメモ。結局 usb は使わないので使用不可にされても問題は無いんだけど、それにしては interrupts が大きい値を示している。

このエラー、結構頻繁に起きていたのでもう少し詳細なログをとっておく。見ての通り "irqpoll" オプション使えと書いてあるんだけどそれ以外の解決策を探したい。

このシステム、「watch -d cat /proc/interrupts」などで見ると割り込み多いね。あとから BIOS の「Advanced」「On-Chip USB Controller」を「All Disabled」にして BIOS の USB コントローラサポートを無効化してみる? または「PnP/PCI」「PCI Slot 1/5, 2, 3,and 4 IRQ Select」を見て手動割り当てを試してみる? または「PnP/PCI」「Assign IRQ for USB」を「Disabled」にしてみる? USB を使う頻度はかなり低いから USB は BIOS で Disabled にしてしまうほうが良いかも。あと何にしても PCI1(sata_sil)とPCI5(ath9k) は (このマザーボードの場合) IRQ 共有される。あとから PCI1 についてるボードを PCI4 に移動させよう。

起動直後の (エラー発生前の) IRQ 割り当て状態のログも欲しいな。USB は使わないからUSBドライバモジュールを /etc/modprobe.d/blacklist.conf に入れればいいんじゃないかという解決策が見つかった。

BIOS の「Advanced」「On-Chip USB Controller」を「All Disabled」にして BIOS の USB コントローラサポートを無効化してみる? に基いて設定変更。uhci_hcd が見えなくなって、IRQ #11 は割り振られなくなった様子。とりあえずこれで運用確認。

一週間程度運用。エラーは出なくなった様子。さらに irq のバッティングを避けるために PCI ボードの入れ替え。

dmesg をチェックする。11 番は usb ポートを占有しているようだ。

コンフリクトのチェック。USB だけみたいなのでとりあえず放置。
