I have experienced this with multiple gentoo-sources kernels (I have not tried vanilla-sources for this), but I truly think the problem is in dhcpcd. Here is what happens: (usbnet is modprobed on boot, hotplug in configured to setup the usb0 interface when it appears) I plug in my iPAQ (running Familiar 0.6.1-rc1, kernel is 2.4.18-rmk1-hh22) do some network operations Remove my iPAQ from the cradle. A few seconds from removal, the kernel panics and all is locked. I say that the problem is dhcpcd for two reasons: - dhcpcd is running as root so it has the access needed to do something illegal - When I install and use pump, I have no such problem From a distro perspective, it would be easiest to fix this by making the bootscripts compatible with pump or another dhcp client.
