Hi again<br>
<br>
I've now tried installing Ubuntu 9 (also tried running the live cd<br>
version of it), but the system still hangs.<br>
<br>
I tried not having any SATA devices, but using an old IDE hard drive<br>
instead - same problem, i.e. system hangs after all the messages about<br>
ehci_hcd.<br>
<br>
I've also tried disabling the USB stuff in the BIOS - no change.<br>
<br>
I can get a "rescue" boot going from the Debian install CD if I append<br>
the "nousb" option to the installation command.<br>
<br>
Does anyone know what GRUB commands the Debian "install nousb" uses. I<br>
believe the nousb thing is just a debian install command, but I'm not<br>
sure that the options are if I tried to pass them to the "kernel"<br>
command in grub.<br>
<br></blockquote><div><br></div>The error that you're seeing vaguely rings a bell and might relate to an incorrectly installed or faulty USB module, which would explain why it boots up with nousb. A google around 'linux ehci_hcd error confirms this. I've seen the problem that you're getting and it relates to the module attempting to get a profile for the module it has identified and on failing, bringing the system down with it as it's involved with storage and is therefore in the core system.<br>
</div><div class="gmail_quote"><br></div><div class="gmail_quote">One workaround might be to install a system with nousb and then install the module using modprobe. To debug it, you should be able to boot from a live CD and see if the hardware USB module is identified using dmesg.</div>
