時間Sun Jan 31 08:34:53 2016
我前兩天將Linux換成 14 的 LTS 除了剛開使沒WiFi可用外 其他都還算穩定,約莫在昨晚更新了WiFi Driver讓WiFi復活 之後有登出一次,沒什麼大礙,但昨晚蓋上電腦後今天打開出現 快淹出來的Consle 畫面 我查國外論壇有看到有人討論 WiFi Driver 造成的 Null Pointer 不過主要都看到在秀 erro Message 所以我還是不太知道要怎麼修復 這個問題 ,提供一些資料給各位大大參考 , 我待會會繼續測試有哪些 error 如果還有什麼需要的資訊也請各位大大告訴我 感謝 ============sudo dmesg kern | grep failed====================== [ 1.007090] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM [ 1.063927] pci 0000:01:00.0: BAR 6: failed to assign [mem size 0x00080000 pref] [ 1.403588] ACPI PCC probe failed.
