|
|
Hello,
I've managed to install 2.6.17-rc3-mm1 kernel on my SunFire 280R and it seems OK.
The problem I have is then I boot this machine I get some "Buffer I/O error on device sdX....." errors.
Below is snap from dmesg command:

See my kernel config based on the one that gust4voz sent here http://leah.haifa.ac.il/~leon/.config-linux-2.6.17-rc3-mm1-280r.txt
What is the problem here?
May be some kernel configuration or I should install some additional software (like hal....)? |

Hello All,
Found this reply of Andrew Morton on some list, that clims that there is no problem with this (http://www.ussg.iu.edu/hypermail/linux/kernel/0307.3/2139.html):

Please just ignore them. They are noise arising from the new readahead
behaviour in the block layer. |
So, I hope there is no actual problem according to the above passage. |
