Problem Details: 2.6.16 introduces USB power budgeting in the Linux kernel, and since then, a fair number of users have observed that some of their devices no longer work in unpowered hubs (this is not a bug, the devices claim that they need more than 100mA). The very least we can do is print an informational message ...

Problem Details: pci_walk_bus has a race with pci_destroy_dev. When cb is called in pci_walk_bus, pci_destroy_dev might unlink the dev pointed by next. Later on in the next loop, pointer next becomes NULL and cause kernel panic. Below patch against 2.6.17-rc4 fixes it by changing pci_bus_lock (spin_lock) to pci_bus_se...
