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.
