Subject: mpc512x USB non-working after kexec
Date: Wed, 2 Sep 2009 11:44:38 +0200 [thread overview]
Message-ID: <20090902094438.GB15401@www.tglx.de> (raw)
Hi John,
on my mpc512x custom board I have non-working USB after the kexec
syscall. I've traced it down to the ehci_turn_off_all_ports() which is
called from within ehci_shutdown(). If I omit ehci_turn_off_all_ports()
it works fine. The content of the portstatus register is the same after
the setup prior the usb-stack takes over so I don't see any difference
here.
Do you see such a behaviour on your board? Unfortunately I don't have
any other "official"/FSL board where I could cross-check and say it is
the HW.
Sebastian
