Description edpil02 2017-08-17 06:26:30 UTC 
Emu10k1 driver stop working since kernel 4.13 update.
Same issue with the last 4.13 rc5 version.
It' Fedora rawhide kernel.

I've no problem with kernel 4.12  and later.

View of dmesg:

[    2.477043] snd_emu10k1 0000:06:00.0: enabling device (0100 -> 0101)
[    2.488677] snd_emu10k1: probe of 0000:06:00.0 failed with error -14

I suspect this is caused by https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d42fe63d58392f29e82e17c02f10e8cd3f45f17f,

This should be reported to the upstream maintainers.

you pushed this right away as 0b36f2bd28d, so i think this is fixed since v4.13-rc6.
