Hi, Here are my observations on omap3evm. 1) With default config file, The kernel boots. If youre seeing junk after a certain point while booting. it could be related to your bootargs console options. (console=ttyS0,115200n8) 2) Sometimes i do get the usual omapfb errors. 3) If i enable cpuidle - the ethernet driver is unable to get an IP address. So it is unable to mount NFS. If i give a statically assigned IP in my bootargs. NFS mount also fails. This happens only when cpuidle is enabled. 4) If i enable SMC debug, i see ethernet interrupts happening, for some reason. NFS mount/getting a dhcp address fails. I am not sure if this is a wakeup issue. Sometimes, if i add some debug prints it works. but this does not work every time. 5) If i boot with rootfs on MMC and with cpu idle enabled. i cannot ping. cpuidle is somehow effecting the network stuff. I also see some rx overruns. is this a wakeup issue?

I'm trying to get my recently received EVM working but I am getting lots of garbage on the serial console on linux-omap HEAD and PM branch on omap3evm.
