linuxgeek: Re: [nslu2-linux] dmesg: attempt to access beyond end of device

That is very strange. I haven't changed anything on my system and if I remember well I never had such kind of problems. My system is running almost four years now.

The mount command returns:

# mount
/dev/root on /initrd type jffs2 (rw)
/dev/sda1 on / type ext3 (rw)
proc on /proc type proc (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/sda1 on /share/flash/data type ext3 (rw)
/dev/sda2 on /share/flash/conf type ext3 (rw,sync)
/dev/sdb1 on /share/hdd/data/USB_D1 type ext3 (rw)

So, if device 08:01 indicates /dev/sda1, then this is the USB flash disk I have attached on port 2.

Do you have any idea about this? Is there any possibility to have a malfunctioning flash disk?

Thanks for your assistance.

i would double check your formatting and partitions, the 08:01 indicates
the first block device partition 1. my guess is that you have a small
partition and a filesystem that thinks it is larger than the partition it
is stored on

this is most likely caused by formatting the disk then partitioning it
with a tool like fdisk. i would recommend you try (if possible) wiping
the disc, partitioning it and then formatting the disk again

if i remeber my device names corectly this should be /dev/sda or
/dev/sda1 for the first partition
