Hi Sarah, I have taken an quickly test. These is OK for s4. And I can't do some tests about S3 since there has the problem about Graphic driver on my platform. -----Original Message----- From: Elric Fu [mailto:elricfu1@xxxxxxxxx] Sent: Friday, April 06, 2012 4:25 PM To: Sarah Sharp Cc: Felipe Balbi; He, Alex; Xu, Andiry; Linux USB Mailing List Subject: Re: [RFC/PATCH] usb: host: xhci: don't re-enable IE constantly 2012/4/6 Sarah Sharp <sarah.a.sharp@xxxxxxxxxxxxxxx>: > There's 11 bug fix patches on my for-usb-linus-queue branch, and > I'd like to make sure that the fixes for one xHCI host vendor don't > break another vendor's host controller. > > Can you please pull and test on your various host controllers (TI, NEC, > AMD, VIA)?

Hi, Sarah. Some problems happened when I used your for-usb-linus-queue branch. First, the OS will hang up when it is resumed from the suspend operation. But the hibernate operation is ok. It is not a xHCI issue. Even if I didn't use the xHCI host controller on the motherboard the issue always happened. It is strange. the 3.3.0-rc7 or 3.3 I used worked fine. My platform is Intel i3 + GIGABYTE GA-H55M motherboard. I built the Kdump + Kexec, but the dump-capture kernel couldn't be started while the issue occurred. Second, a kernel panic randomly occurred When some superspeed devices were attached to the VIA host. I met the kernel panic twice. the dmesg log: [ 37.544629] EXT4-fs (sda2): re-mounted.
