USB HDD or filesystem bugs?

[Peter Teoh]

I am on the latest linus git tree:

/hdc1/download/2.6/linux-2.6-latest>git describe
v2.6.28-rc3-54-g75fa677

OS: is SUSE 10.2, with two external USB harddisk attache, and
seemingly it keep reseting itself.....and the version of OS is built
yesterday:

hardware is AMD ASUS motherboard.

/hdc1/download/2.6/linux-2.6-latest>uname -r
2.6.28-rc3-bigsmp-00031-ga75952b

and then the OS mount the devices again and again with dmesg errors like:

"ls" the /media/disk-25/ gives:

Remounting filesystem read-only
/hdc1/download/2.6/linux-2.6-latest>ls /media/disk-25
ls: reading directory /media/disk-25: Input/output error

any specific direction I should look for?

Full dmesg output attached.

i can do a git-bisect......but then it will take me till monday to do
again....perhaps i will try it out on two other different machine.
