For some reason, /sys/fs/pstore has 537 files in it, all called 'console-efi',
all having inode number 8021, and all consisting of the same one line:
[/sys/fs/pstore] cat console-efi
[ 1.567734] pci 0000:00:1c.1: PCI bridge to [bus 03]
[/sys/fs/pstore] ls | uniq -c
537 console-efi
[/sys/fs/pstore] cat console-efi
[ 1.567734] pci 0000:00:1c.1: PCI bridge to [bus 03]
[/sys/fs/pstore] grep . * | uniq -c
537 console-efi:[ 1.567734] pci 0000:00:1c.1: PCI bridge to [bus 03]
[/sys/fs/pstore] ls -li | head

I can remove one, and then it gets even more weird:
[/sys/fs/pstore]1 rm console-efi
[/sys/fs/pstore]1 ls | wc
536 536 6432
Goodie - one less. Let's try again. 'rm c<tab>' completes to console-efi
[/sys/fs/pstore]1 rm console-efi
rm: cannot remove 'console-efi': No such file or directory
[/sys/fs/pstore] ls | wc
536 536 6432
[/sys/fs/pstore]1 ls -li console-efi
ls: cannot access console-efi: No such file or directory
[/sys/fs/pstore] ls -li 2>&1 | uniq -c
536 ls: cannot access console-efi: No such file or directory

Take a look at this thread: https://lkml.org/lkml/2013/10/30/83
I think there were some bugs in the console-efi code a while
back - perhaps you ran a kernel had the bug and made all these
duplicate entries?

The cited patch pair isn't in linux-next-20140409, but applied with a few
1-line offsets. Boothing the result was much better. 'git blame' doesn't
indicate anything changed between next-0303 (busted) and next-0409, so
I have to conclude that Madper Xie's patch is an improvement.
Madper: Feel free to stick this on the patch:

The gory details:
I now have different filenames and inodes, with different contents, rather than
duplicates:
ls -li /sys/fs/pstore | head
