After some bingo moment, seems the solution is easier than expected: andi@andinet:~$ ls /tmp/initrd_extracted/lib/modules/3.7.0-rc5+/kernel/drivers/usb/host/ ehci-hcd.ko ohci-hcd.ko uhci-hcd.ko xhci-hcd.ko andi@andinet:~$ ls /lib/modules/3.7.0-rc5+/kernel/drivers/usb/host/ ehci-hcd.ko isp116x-hcd.ko sl811_cs.ko uhci-hcd.ko ehci-pci.ko ohci-hcd.ko sl811-hcd.ko whci hwa-hc.ko r8a66597-hcd.ko u132-hcd.ko xhci-hcd.ko So it's probably only that the initrd simply fails to ship the ehci-pci.ko module (I could verify this by extending initrd content, BTW). Now the question would be: are modules listed in a static list on initramfs package/config side, or does the kernel fail to signal the list of required modules properly? (e.g. did some config-side files fail to get upgraded for this dependency??) So maybe it's not a "regression" per se, but it's at least a grave usability issue on kernel upgrade which should be handled as benignly as possible (i.e., without any disruption).
