This is running a 32-bit application on a 64-bit OpenSuSE 10.2 installation with no USB-attached devices.
It looks as if the sampler has lost track of the instruction pointer values; the hottest point in the profile is the kernel function 'usb_storage', and if I double-click on that it tells me that all the events occured at address 0x00000000; I suspect usb_storage has been mapped at that address and that's why everything's showing up there.
Has anyone else seen this? Even better, has anyone else fixed this?
