[Bug 275351] Re: slow boot on intel DG45ID

Fri Mar 6 15:24:15 UTC 2009

Would the patch in http://bugzilla.kernel.org/show_bug.cgi?id=12148 be
acceptable in Ubuntu kernel? It adds a new kernel command line parameter
ehci_ho_to (EHCI hand-off timeout) which defaults to 5000 ms in the
patch. The patch can be seen at
http://bugzilla.kernel.org/attachment.cgi?id=20442&action=view

The ehci_ho_to kernel parameter could be used with the motherboards that
suffer from this bug to improve the speed of the boot process. It should
be noted that the timeout is not defined in any specification so there's
no safe default. The timeout of 5000 ms in the current kernel just seems
to work for all hardware. Some (most?) hardware could use much smaller
timeout.
