各位大神好，小弟遇到ubuntu12.04时不时死机的情况，恳请各位朋友看一下

[freestyle4568]

情况描述：本人连续试了14.04.1和12.04，都是不定时的就死机了，原先以为是显卡问题，现在发现不是，貌似是无限网卡的驱动问题，在syslog里面都是写的networkmanager的问题错误，还有dnsmasq软件的问题。
问题描述：
1.无线网卡驱动问题可能导致死机吗？
2.如何解决如下的syslog显示的错误问题。

kernel方面的错误包括：
Oct 19 17:30:41 freestyle4568 kernel: [ 0.520751] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM
Oct 19 17:30:41 freestyle4568 kernel: [ 0.556987] acpi PNP0A03:00: _OSC failed (AE_NOT_FOUND); disabling ASPM

非常感谢各位朋友的帮助！！！由于本人最近在搞软件项目，所以非常着急，再次恳请各位朋友帮忙，不慎感激！

都是不定时的就死机了

1. 暫時解決方案
開機時 加一些核心參數
http://apexu.com/apexu/tw/modules/publi ... ?itemid=14
https://help.ubuntu.com/community/BootO ... el_Options
看看能否開機登入桌面
多試幾次 看看哪個參數有效 通常跟顯卡有關
2. 如果能登入桌面
2-1. sudo lshw -numeric -class network
2-2. sudo lshw -numeric -class video
把結果複製貼上來

朋友好，NVIDIA340的驱动非常完美地安装OK了。
下面还有什么问题吗？
因为以前也安装过331的驱动，不过后来还是死机了，不知道这回怎么样？
下面是我开机的日志错误报告：

朋友好，有线网卡和无线网卡都按照你说的换好了。不过换好后今天在打开网页的时候又死机了，鼠标消失什么的，在kernel日志中没找到当时什么异常。
下面是现在日志l中的异常，比之前少很多了呢：

你是不是 安裝 freestyle4568 打包的 Linux kernel ?
缺少 r8101 驅動模組 的簽署
sudo ifconfig -a
看看 無線網卡 有沒有成功啟動

[freestyle4568]

1.sudo dpkg -l | grep dnsmasq :
ii dnsmasq-base 2.59-4ubuntu0.1 Small caching DNS proxy and DHCP/TFTP server

2.sudo dpkg -l | grep network-manager
ii network-manager 0.9.4.0-0ubuntu4.4.1 network management framework (daemon and userspace tools)
ii network-manager-gnome 0.9.4.1-0ubuntu2.3 network management framework (GNOME frontend)
ii network-manager-pptp 0.9.4.0-0ubuntu1 network management framework (PPTP plugin core)
ii network-manager-pptp-gnome 0.9.4.0-0ubuntu1 network management framework (PPTP plugin GNOME GUI)

3.有一次安装了kernel。之前装wl的时候在终端里安装了sudo apt-get install 3.13的kernel.
这个会导致没有模块的签署吗？会不会影响系统稳定性啊！

4.sudo ifconfig -a

無線網卡 已經啟動 獲得 IPv4 並且有接收/送出資料包

補充
Ubuntu 預設由 Network Manager 管理上網
Network Manager 預設同一時間 只能有一個網卡 連上網路
其它網卡 連上網路以後 會自動斷線 呈現待線中

[freestyle4568]

好吧，我现在确实一直用的是无线呢
那dsnmasq的错误报告和ASPM的错误报告是不是没有办法处理啊！

[poloshiao]

那dsnmasq的错误报告和ASPM的错误报告是不是没有办法处理啊！

如果不影響使用 暫時不理它 應該沒關係
如果一定 要打破砂鍋問到底 也可以折騰折騰

[freestyle4568]

好吧，那就不折腾了，赶紧搞内核编程吧，前几天把我折腾死了！！！
系统现在应该没问题，有问题再请教你把 ，THANK YOU VERY MUCH
