Grub2 has a limit of 64 bytes for the device path. Some types of devices have path longer than 64 bytes. 

For example, we have a device with the following path:
/io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/pci1014,0339@0/sas/disk@0

In the grub2's rescue console, an 'ls' shows the complete device path, but 'ls -l' throws an error showing a truncated device path.

grub rescue> ls
(ieee1275//io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/pci1014\,0339@0/sas/disk) (ieee1275//io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/pci1014\,0339@0/sas/disk,msdos3) (ieee1275//io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/pci1014\,0339@0/sas/disk,msdos2) (ieee1275//io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/pci1014\,0339@0/sas/disk,msdos1) (ieee1275//io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/pci1014\,0339@0/sata/disk) (ieee1275//packages/gscsi/disk) 
grub rescue> ls -l                          
error: disk `ieee1275//io-hub@3efe00000000/pciex@3efe00080000/pci@0/pci@0/pci@6/
pci101,msdos2' not found.

Hey, what is the progress on this?

Comment 2 Phil Knirsch 2013-02-08 14:36:44 UTC

Can't see the patch in the latest grub2, so moving to rawhide.

Thanks & regards, Phil

Comment 3 Fedora End Of Life 2013-04-03 18:20:51 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
