Ubuntu 10.10 Netbook Remix 访问平板电脑SSD出错

[iquestions]

求助各们高手！！

本人非专业人士，只因有单平板出到国外，客人使用时发现访问SSD时会出现只读错误．
因为本人不懂Linux, 现将客人原文贴出，望高人搭救．

机器是用的Ｘ８６架构的，N455的CPU.



The problem on the Tablet of the unmount of the disk is occurs randomly, the error happens to us on "Ubuntu 10.10 Netbook Remix" with linux kernel 2.6.35 and 3.5.0. We do not know the type of file that is written when it unmount. In addition to the e2fsck and badblocks software, the disk was analyzed in the "Equipo 2" and showed no abnormality, ie this ok.

The information is retrieved corresponds to dmesg on some equipment:
