すずきと申します。 11月13日にcvsupした6-STABLE上で、 ・ノート機(松下CF-B5ER)において ・ACPIが有効な状態で ・/usr/ports/misc/dnetc を稼動させ、 ・稼動中にバッテリーを脱着する
とカーネルパニックが起きます。 CF-S21という超古いノートに7-CURRENTを突っ込んで そちらでやってみても同様の結果でした。バッテリーを 装着したとたんにXが落ちてリブートします。 どこから手をつけていいものやら見当もつきません。 ご教授くださればありがたいです。 - - - - - Fatal trap 18: integer divide fault while in kernel mode instruction pointer = 0x20:0xc0488a97 stack pointer = 0x28:0xccc2fb90 frame pointer = 0x28:0xc25f18c0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 933 (dnetc) trap number = 18 panic: integer divide fault Uptime: 21m26s Cannot dump.
