Hello,
After upgrading from 2.6.18.3 to 2.6.19.2 on an x86_64 machine I noticed
that the EHCI USB host is unable to work properly after a kexec invocation.
This makes it impossible to mount the rootfs in the configuration I'm using.
According to the prints, the irq changes from 23 to 10.
NOTE: Since the device is already connected at boot, I've added a patch
that disables the scanning delay for the first detected device, in order
to shorten the time it takes for the boot process. It worked on 2.6.18.3,
so I wonder what has changed...
