FreeBSD質問所コミュの「管理人さんタイトルお願いします」

FreeBSD がよく操作不能に陥り困っています。
多分、Linux でいう "Kernel Panic!"の状態だと思わます。
一度、コンソールが利かなくなったときに LAN 上から sftp や ping をかけてみたが、反応がありませんでした。(もちろん、sftp や ping が使える設定はしてあります。)

次のデバイスを使ったときに起こるのかと疑ってみましたが、DVD-R ドライブ、PC カード、LAN
どれも再現できません。

一時期 Safe mode で安定していたのですが、最近では Safe Mode でも操作不能になります。
始めは付属の USB マウスを刺していても起動していたのですが、最近は USB マウスを刺していると、通常モードでも Safe Mode でもブート途中にメッセージが止まって起動すらしません。途中でUSB マウスを刺してみると操作不能に陥ります。

ただ、何度も異常な終了の仕方を繰り返してしまっているため、ファイルが壊れていって環境が変わっていっている可能性があります。

推測が多く申し訳ありません。
