Re: [Xen-users] dom0 USB failing with "ehci-pci: probe of 0000:00:1d.0 failed with error -110"

[Robin Lee <robinlee.sysu@xxxxxxxxx>]

After a git-bisect test, the commit 724b55f48a6c9fca00ddeeca5a130657680caf0b is found the first one that introduces this issue.

And that also suggests that setting 'mwait-idle=false' works around the issue. And this is also tested.

So it may be a bug in 724b55f48a6c9fca00ddeeca5a130657680caf0b?

Hi all,

I recently met the same problem of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=748052
Also xen-devel list:
http://lists.xenproject.org/archives/html/xen-devel/2014-05/threads.html#02084

I copied the subject of this message.

I tested previous versions of xen and found the issue was introduced in xen 4.3.0. Any later versions up to 4.6.1 does not fix this issue.

Dom0 Linux kernel version is 3.10 from XenServer 6.5SP1.

I am new to xen debugging and willing to provide any additional information if needed.
