Hello kernel list,
I don't know if this is the right list for problems with kernel modules
and bugs - if not please tell me where I can find the kernel development
mailing list to report this.
So here is my problem:
I get errors when I try to copy files to my usb harddisk. In the first
minutes it works fine but then I get following errors for each block to
write on the disk:
Jan 20 10:07:53 orclex kernel: SCSI error : <1 0 0 0> return code = 0x70000
Jan 20 10:07:53 orclex kernel: end_request: I/O error, dev sda, sector

Jan 20 10:07:53 orclex kernel: Buffer I/O error on device sda6, logical
block 190016
Jan 20 10:07:53 orclex kernel: lost page write due to I/O error on sda6
Jan 20 10:07:53 orclex kernel: SCSI error : <1 0 0 0> return code = 0x70000

block 190017
Jan 20 10:07:53 orclex kernel: lost page write due to I/O error on sda6
...
I'm using kernel 2.6.10 and the error appears when I load the ehci_hcd
module for USB 2.0. When I don't use this module (so I can only use usb
1.1) I get no errors while copying files to the usb harddisk.
I have got an ALi PCI-Card for USB 2.0:

Is this a known bug and does any patch exist?

This is the right list, but you might want to post this to the
linux-usb-devel mailing list, where the usb-storage driver authors are.
They should be able to help you out.
good luck,
