メモリ不具合疑惑

[ カテゴリ： MacOSX ]

最近、OSXの不具合ばっかりですが、また落ちました。

とはいっても、今度は前回までとちと様子がちがう。

panic(cpu 0 caller 0x001944A8): pmap_enter: null pv_list!
Backtrace, Format - Frame : Return Address (4 potential args on stack) 
0x363fbd28 : 0x128d08 (0x3c9ac4 0x363fbd4c 0x131de5 0x0) 
0x363fbd68 : 0x1944a8 (0x3cd0cc 0x1519000 0x0 0x0) 
0x363fbdf8 : 0x160ab6 (0x657ac70 0x1519000 0x0 0x76783) 
0x363fbf48 : 0x1a350e (0x52cc000 0x1519000 0x0 0x1) 
0x363fbfc8 : 0x19a864 (0x5bbd180 0x0 0x19d0b5 0x5442960) No mapping exists for f
rame pointer
Backtrace terminated-invalid frame pointer 0xbfffe808

これ、まさにターミナルからmakeって打った瞬間に落ちたんですけど、さすがに今どきpmapまわりが腐ってることはないだろうと。そんなことがあったら、先日のmbufよりたちが悪い。しかも、前日の夜にFinderは激しく落ちるわ、gccは転けまくるわ(しかも転ける場所は不定)、Terminalも落ちるわのお祭りでした。なので、このpanicでさすがにこれはメモリが腐ってるでしょうと疑わざるを得なくなったわけです(というか、重い腰をあげたって感じ)。

さて、i386なら(って、MacBook Proもi386だけど、EFIじゃないふつーのBIOSならってことね)memtest86で終わりなんですが、いかんせんMacBook Proなのでどうしたものかと。で、ちょっと探してみるとRemberというメモリチェッカがありました。本家はここで、日本語化したのはMacのメモリ専用ショップ(これもすごいと思うが)のマックメムさん。本家から取得してもたぶん日本語化されていると思います。メモリチェッカなので英語のままでもいいと思いますけど。

RemberはOSXの上で動きます。本当はこんなでかいOSの上で動かさない方がいいんだけど、面倒な気分でいっぱいなのでこれでいくことにします。以下、一部整形済み結果。

…すげえ、ぼろぼろだ。このMacBook Proは1+2の3Gなんですけど、一応抜き差ししてみる…のついでに、とりあえず1GにしてRemberを走らせてみよう。

ほほう。じゃあ次に、2Gにしてやってみよう。てか、石がひとつやられてるだけだと思うんだけど、運が悪ければOSがあがることすら無理かもしれず…が、なんかあがったので、以下Remberの一部整形済み結果。

ぼろぼろー。あと考えられるのは、Remberが2Gのメモリと仲悪い…なんてことは考えにくいでしょうが、一応3GのMBPのひとにもテストをお願いしました。待て次号！

ってわけで、現在1G状態…
