Yeah, pretty sure initrd is loaded, otherwise it wouldn't be able to access the CD to load packages listed in LRP= above. >> >> contents of <initrd root>/boot/lib/modules directory: >> >> -rw-r--r-- 1 root root 37512 2009-02-07 14:37 cdrom.o >> -rw-r--r-- 1 root root 20908 2009-04-28 14:19 ehci-hcd.o >> -rw-r--r-- 1 root root 36596 2009-02-07 14:37 ide-cd.o >> -rw-r--r-- 1 root root 135908 2009-02-07 14:37 ide-core.o >> -rw-r--r-- 1 root root 1075 2009-02-07 14:37 ide-detect.o >> -rw-r--r-- 1 root root 18236 2009-02-07 14:37 ide-disk.o >> -rw-r--r-- 1 root root 22199 2009-02-07 14:37 isofs.o >> -rw-r--r-- 1 root root 77786 2009-04-23 16:38 scsi_mod.o >> -rw-r--r-- 1 root root 15828 2009-04-23 16:38 sd_mod.o >> -rw-r--r-- 1 root root 81022 2009-04-23 16:35 usbcore.o >> -rw-r--r-- 1 root root 22776 2009-04-28 17:10 usb-ohci.o >> -rw-r--r-- 1 root root 69776 2009-04-23 16:36 usb-storage.o >> -rw-r--r-- 1 root root 26392 2009-04-23 16:36 usb-uhci.o >> -rw-r--r-- 1 root root 13930 2009-02-07 14:37 vfat.o > > You got many more modules than I found on the initrd, this is > suspicious.

I needed to increase the usb_wait value in /var/lib/lrpkg/root.linuxrc in my initrd package. Default value is 1, I increased that to 3. Works as expected now. I remember (now) having to do this when I first set up my v3.0-Beta2 disks. Guess I didn't take good enough notes back then. The machines I'm running LEAF on here are way overkill for the job, so they run through the boot process too fast to allow for proper USB initialization, I guess. Thanks again.
