LCD display sometimes fails to resume after being blanked
The "Exquisite" splashscreen utility conflicts with getty on tty1 and dumps a lot of error messages to the console. These errors can be easily ignored.
Peripherals
No hotplug on USB ports connected to SB-T35 USB Hub (connector P17) with default kernel binary
Workaround 1: append usbcore.autosuspend = -1 to the kernel command line
Workaround 2: connect low/full speed USB devices to P17 connector before booting CM-T3530. Use P21 connector for hotplugable high speed USB devices
