iPod and FC3 Now Working!
December 10, 2004 5 Comments
I am happy to report that this issue seems to be fixed as of the latest 2.6.9-1.681_FC3 FC3 kernel (although I don't see a specific mention in the Changelog). This means that I will no longer have to build RPMs for this. Yah!

Hi Jeremy,
I recently installed Fedora Core 3 (2.6.9-1.667) and directly updated it with the newest kernel (2.6.9-1.681_FC3). Unfortunately, I cannot mount my Ipod mini, since /lib/modules/2.6.9-1.681_FC3/build/.config file still has CONFIG_EFI_PARTITION=y. So I'm not sure if this is inherent to the 681_FC3 kernel or whether this is caused by the fact that I updated an older kernel instead of installing a brand new one.
This still leaves me without access to my Ipod, and I've not seen a description on how to recompile the kernel that gave me the idea that I could do it myself. Do you know of a webpage that describes how to recompile the kernel?
Regards,
Cees
Regulus,
The kernel on my FC3 machine is also 2.6.9-1.681_FC3 (although it's smp). While CONFIG_EFI_PARTITION=y is present in /boot/config-2.6.9-1.681_FC3smp, mounting my iPod works straight away. This machine was also an upgrade, so I doubt that has anything to do with it. While I don't see anything in the changelog, it's likely that they left the EFI stuff in and just corrected the actual problem in the code. What error are you getting when you try to mount your iPod?

Thanks for your reply Jeremy.

It, correctly, sees the 2 partitions, but gives a load of those “Buffer I/O errors on sdb, sdb1 and sdb2.
When I then try to mount the ipod, with “mount /dev/sdb2 /media/ipod/ -t vfat” I get “mount: /dev/sdb2: can't read superblock”. In /var/log/messages I find:
end_request: I/O error, dev sdb, sector 80325
FAT: unable to read boot sector
These messages are rather similar to what was mentioned here http://www.linuxquestions.org/questions/showthread.php?postid=1086262#post1086262

Might this be related to the fact that my kernel does not load the usb-core module (it does appear to load usb-storage and usb-uhci).

Regulus,
Please check the kernel version. I'm getting the same error with FC3, but on an earlier version of the kernel than Jeremy has.
Cheers,
