開機一段時間，突然變得很慢？console也怪怪??

[hwchen]

我的故事是這樣的：
前一陣子，老板買了幾台ibm的機器，很小台，型號好像是s50吧…cpu是2.8的p4
，有雙通道的ram，和hd…我在其中一台拿來當桌上型用，我還記得當初是用2004.1裝的，那個時候用的kernel是ck-sources/2.6.7-rx，一切正常，所有的東西都很正常，可是後來當我換了新的ck-2.6.8-rx和ck-2.6.9-rx之後，就再也沒有正常過了。如果一開機的話，是正常的，可是開了一段時間之後，就變得怪怪的，所以的動作都很慢，在console下按住鍵盤他也不會repeat某個鍵，有時還會出現對時的問題，就是系統時間變成是1970-xx-xx-xx，然後所有的動作都會變得很慢，如果是在x下的話，原本的游標會變成是一團像是字又像是符號的東西，還是x就會死掉，一定要從網路進去reboot（因為完全切不回console），接著reboot又變得很慢很慢，stop一些services和umount　partition都變得很慢，大概要十分多鐘之後才關的了機，重點是：去看/var/log/messages完全沒有錯誤訊息，超奇怪，原本以為是我把gcc從3.3.x升到3.4之後compile kernel的問題，沒想前幾天換了顆新hd，重裝gentoo的時候，用2004.3裝了之後還是一樣的問題，不知道有沒有人遇到這樣的問題過，我在懷疑是不是硬體的問題，既然hd換了，會是ram或cpu的問題嗎？還是我在compile東西的時候，cflag寫的太多，以下是我的cflag：-O3 -march=pentium4 -mfpmath=sse -msse2 -mmmx -fforce-addr -fomit-frame-pointer -funroll-loops -frerun-cse-after-loop -frerun-loop-opt -falign-functions=4 -pipe”，還是說是什麼其他的問題呢？

oops…我忘了說了，即使在用livecd安裝的時候也會出現這樣的情形，總是有一個共通的錯誤會產生：
checking whether build environment is sane... configure: error: newly created file is older than distributed files!
Check your system clock
接著我去查系統的時間：
# date
Fri Nov 19 08:16:28 Local time zone must be set--see zic manual page 2004
而且每次系統的時間都會亂跳，設好了之後就又跳開了
該不會是主機板的問題或是主機板的電池沒電了吧…

謝謝scsi兄的回覆，我這兩天比較忙，等會報告完再處理kernel的事情，不過我昨天在使用的時候發現一個徵兆，以下是/var/log/everything/current:

每次login的時間跳來跳去，整個系統也變得很慢…（有那麼多message是因為我開了kernel hacking）
現在的是間是2004年十一月二十五日十三點十四分，可是我在系統用date卻出現
Thu Nov 25 00:26:29 CST 2004
如果是一般使用都的date：
Wed Nov 24 23:14:57 CST 2004
小弟沒有遇過這個問題，我等一下會reboot去check bios裡的時間，如果各位高手可以給小弟一些指點的話就感激不盡了

[hwchen]

嗯，我今天把kernel換到gentoo-dev-2.6.9-r6之後的情形還是一樣…system clock會突然就停在某個時間點，然後系統就掛點了…現在還是不知道為什麼…

[hwchen]

嗯，幾天前終於硬著頭皮叫ibm的人來換主機板，沒有想到一切就正常來，看來是主機板的錯…

ps：不過以後ibm就沒有桌上型和筆記型電腦了吧…變成聯想…大陸貨…嗯…我得三思
