WARNING: at fs/sysfs/dir.c:463 sysfs_add_one+0x4a/0x50()

[A.S. Pushkin]

I hate to post this question, but I'm unsure what it means and this has been occurring on the last 2 kernel upgrades for me. I'd appreciate if anyone is able to tell me what I am leaving out or how to correct this.

This taken from dmesg.

Thanks!

well, seems you have some kind of duplicate filename that prevent creation of the wanted filename.

1/ a kernel bug with a race condition you meet
2/ a program bug that is calling that kernel function in a bad context, manner....
3/ i prefer that one : a bad fs that respond erratic datas to a kernel function, it's time to fsck that fs
