i first ran into this with the install. i would see a message about disabling one irq and then everything hung. 14 thousand tries later i noticed that in the bios that irq was related to one of the usb devices. i unplugged my logitech 4000 webcam, and my APC ups from the usb connector, and suddenly the install went right on with no problems. then, i ran into this just now during a reboot. i rebooted. during the startup, it said configuring hardware, and then that was it. sorry -- i didn't write it down and at that point you can't copy and paste! :-( so. when i unplugged the cam, the boot went right on. just like the install. later when i cranked up motion to monitor that cam, i get the following from pwc in syslog: Jun 15 22:42:40 junior kernel: pwc Failed to set LED on/off time. Jun 15 22:42:40 junior kernel: pwc Failed to allocate decompress table. Jun 15 22:42:40 junior motion: [1] Failed to open video device /dev/video2: Cannot allocate memory i have no clues. anyone have a take on this? certainly can't go around and unplug the cam every time i need to reboot. BTW, this is a system that worked in FC1-FC2-FC3 with no problems. alexander dalloz! WHAT is the answer, oh one of great knowlege ????????? :-) john
