我的FEDORA 8,本身是2.6.23的內核,里邊的無(wú)線(xiàn)網(wǎng)卡驅動(dòng)不太好,我下載了2.6.28的內核給安裝了
現在有個(gè)問(wèn)題,關(guān)于筆記本自帶的MMC讀卡器的
2.6.28的內核里邊我把MMC的驅動(dòng)靜態(tài)編譯到內核了,系統剛啟動(dòng)時(shí),MMC卡插到讀卡器后,系統可以自動(dòng)掛載MMC卡,并能在桌面上顯示MMC卡的圖標,并且會(huì )彈出MMC卡文件夾
問(wèn)題就是:系統啟動(dòng)過(guò)了一段時(shí)間后,系統就不能自動(dòng)掛載MMC讀卡器了,但是此時(shí)可以手動(dòng)掛載。而且此時(shí)fdisk -l,硬盤(pán)分區一下就列出來(lái)了,后面要等半天才能列出MMC的分區,很郁悶,不知道為什么。
下面是dmesg | tail的輸出:
[root@localhost ~]# dmesg |tail
