Hi, We have a computer acting as a server that locks hard (PS2 keyboard stops responding, prompt never returns, boot gets no further) when USB2 is enabled on FC3 (there were no lockups with FC1). I finally traced this down to being some sort of interaction between udev and USB2. The following steps reproduce the problem: Boot the kernel with init=/bin/sh mount -n -t proc /proc /proc mount -n -t sysfs /sys /sys /sbin/start_udev /sbin/modprobe uhci-hcd The machine will hang and not get any further nor will it respond to a ctrl-alt-del or sysrq commands. modprobing uhci-hcd before starting udev causes the problem to disappear as does disabling USB2 (but leaving USB1 on) in the BIOS. Kernels tested are kernel-2.6.9-1.667 and kernel-2.6.10-1.766_FC3. lspci prints the following USB controller: 00:07.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 16) Does this sound like a known issue? -- Sitsofe | http://sucs.org/~sits/
