mtd errors on boot OpenRD "ultimate"

[Rick Thomas <rbthomas@pobox.com>]

For a few seconds during the boot process on my OpenRD "ultimate",  
running Debian Squeeze, I get hundreds of messages in syslog like this:

Buffer I/O error on device mtdblock0, logical block 0
Buffer I/O error on device mtdblock0, logical block 8
end_request: I/O error, dev mtdblock0, sector 0
end_request: I/O error, dev mtdblock0, sector 128
end_request: I/O error, dev mtdblock0, sector 16
end_request: I/O error, dev mtdblock0, sector 64
end_request: I/O error, dev mtdblock0, sector 8
loop: module loaded
uncorrectable error :


Does anybody know what causes them?  Is there anything I can (or  
should) do about them?


Thanks!

Rick
