Hi Alan, I tried doing the rmod/modprobe fix for the ehci-hcd problem but had no luck.
Anything else I can do to figure out the story? I also changed all the usb-related drivers to be modules rather than compiled-in as they were originally. I re-confirmed that the drive works fine once linux has finished booting. I also re-confirmed that the same on-disk configuration ( kernel, initrd, ... ) boots fine on the Lexar but not on the Sandisk. The Sandisk boots properly on my Thinkpad T30. So the problem seems to only occur at boot-up ( or only when the Sandisk is the first drive to be used with ehci-hcd ) on the VIA EPIA MII10000 motherboard. Here's how I modified the /init inside the initrd to do what you suggested: log_begin_msg "Loading modules" load_modules log_end_msg log_begin_msg "Unload and reloading ehci-hcd" rmmod ehci-hcd rmmod ehci-hcd sleep 20 modprobe ehci-hcd sleep 10 log_end_msg Cheers, -Dan Alan Stern wrote: > On Mon, 15 May 2006, Dan Sandberg wrote: > > >> When I tried it the first time, I booted of the working USB drive and >> then inserted the second USB drive.
