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 1555604 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 Jan 20 10:07:53 orclex kernel: end_request: I/O error, dev sda, sector 1555605 Jan 20 10:07:53 orclex kernel: Buffer I/O error on device sda6, logical 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:

Here is an extract of my /var/log/syslog while loading my usb storage device:

Is this a known bug and does any patch exist?
Thanks in advance,
