xHCI host controller not responding, assume dead

[Waz]

Hello,

I see this message that appear :

xHCI host controller not responding, assume dead
HC died; cleaning up

There is a patch available that is included in 4.18 but it would be nice, if it's possible, if it could be included in current Ubuntu kernel.

Here is the patch :

https://patchwork.kernel.org/patch/10479909/

Commit to 4.18 :

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.18-rc4&id=229bc19fd7aca4f37964af06e3583c1c8f36b5d6

Note that it looks like it depends on commit bcaa9d5c5900 ("xhci: Create new structures to store xhci port information") at least, which is a non-trivial patch.

There is more infos here :

Thanks !

Should be the same one as LP: #1763594.

If it's fixed in 4.15.0-29 so it's not the same since I still have the error.

[Kai-Heng Feng (kaihengfeng)]

The fix is not yet in 4.15.0-29.

[Waz (paviluf)]

Ok, do you know in what version the fix will be for me to test ?

[Kai-Heng Feng (kaihengfeng)]

 I've already make a backport [1] for older kernels. It should be picked in next kernel version.
