I am unable to boot a Dell PowerEdge R210 if ehci-pci module is built into the kernel. The _ marker just blinks, after few minutes nothing has changed. The last messages it does display that I can get thru iDRAC is: ehci_hcd: USB 2.0 'Enhanced' Host Controller ehci-pci: EHCI PCI platform driver ehci-pci 0000:00:1a.0: EHCI Host Controller ehci-pci 0000:00:1a.0: new USB bus registred, assigned bust number 1 ehci-pci 0000:00:1a.0: debug port 2 ehci-pci 0000:00:1a.0: irq 22, io mem 0xdf0fa0 if I disable the USB support, the kernel does boots just fine. Booting Ubuntu 14.04's kernel 3.13.0-24-generic does not seems to suffer from this very problem.
