After much research on the internet on how to get my iPod working, I compiled a custom kernel without
EFI support, but the problem still persists.
In more detail:
Harware: Sony Vaio Laptop + iPod with Clickwheel (20gbs)
Sowftare: Ubuntu 6.06 (Dapper).
Original Problem:
- iPod automounts (/media/ipod) when plugged and filesystem can be viewed with nautilus / command line
- Trying to copy data (using cp or gtkpod) from iPod hangs the process after a few seconds. System logs reports "Buffer I/O errors" See log at the end.
Steps taken to fix (in summary, I have been at this for almost a month):
- Plugged iPod directly to laptop port (without USB hub).
- Compiled custom kernel with no EFI support. (2.6.15)
The problem is still there when using the kernel without EFI support, which seems to fix the issue for most people.
Does anybody have any other ideas on how to fix the problem?
Thanks for the help!
