PEXUSB3S44V メモ

www.startech.com

めっちゃお世話になっているUSB3.0ボードの PEXUSB3S44V だが、linux kernelを4.19から5.3に上げたら動かなかった。
ルネサスのUSB3.0チップを4個積んだ贅沢なボードで、これで裸族のスカイタワーを4台接続して格安ストレージサーバーにしている。（ただし、大量に書き込みするとUSB-SATA変換チップでエラーが頻発するのでできるだけ書き込みはしない）
予備の同じ型番のUSBボードを別のPCに刺して動かしてみたら5.3でも普通に動いているので、個別のボードの問題かもしれない。

(追記)
ボードを入れ替えても起きたので別の問題みたい。
serverfault.com
こちらを参考に、カーネルパラメーターに iommu=soft pci=nomsi intel_iommu=off を入れたら5.3でも動くようになった。
エラーはこんな感じだった。

xhci_hcd 0000:04:00.0: Abort failed to stop command ring: -110
xhci_hcd 0000:04:00.0: xHCI host controller not responding, assume dead

正常に動いている方の lspci の結果をメモ。
