Getting "I/O error, dev mtdblock1, sector 0" errors at boot

Edit: I see that 1) search is a good thing, and 2) this is not a problem. Never mind :)


I have a Dockstar running Debian squeeze as installed by Jeff's script. This has been working well, 24/7, for about two months. The Dockstar is used only for rtorrent, and it has been very stable. We had a power outage again today, so I rebooted the Dockstar and launched rtorrent. After a while, rtorrent crashed, which is very unusual indeed. So I rebooted the Dockstar again. Then I did dmesg and saw this in the output:

[  651.128724] uncorrectable error : 
[  651.132017] end_request: I/O error, dev mtdblock1, sector 0
[  651.137803] Buffer I/O error on device mtdblock1, logical block 0
[  651.144201] uncorrectable error : 
[  651.147447] end_request: I/O error, dev mtdblock1, sector 0
etc., etc.

What does this mean? Is there any way to fix this? Or is it normal?

Thank you!

Sorry for pushing this...
I have the same error in my dmesg and would like to know, too. The box itself seems to be working fine, but messages like that always make me shiver :)
Especially since the whole process takes about 7 seconds of the boot-up time.
[ 16.442539] uncorrectable error :
[ 16.445846] end_request: I/O error, dev mtdblock1, sector 0
[ 16.451626] Buffer I/O error on device mtdblock1, logical block 0
...
[ 23.673949] uncorrectable error :
[ 23.677205] end_request: I/O error, dev mtdblock1, sector 0
This repeats exactly 516 times with different sector numbers, but mostly "0"

Any hints where to look at?
Thanks!

After I posted this thread to the forum, I did a google search, and that found this thread, which is also on this forum:

Apparently it's normal. It looks weird, but my Dockstar is still running:

Uptime: 22 days, 00:50:18

which basically means that it's been 22 days since the last power outage :)
