Hi!
I'm getting this warning during boot:
[ 3.413299] gpio gpiochip1: Persistence not supported for GPIO 0
[ 3.419494] cpcap-usb-phy cpcap-usb-phy.0: could not initialize VBUS or ID IIO: -517

(and then cpcap does not work). Is my configuration missing something?
Later I get warnings about framedone interrupt not being done (IIRC)
from HDMI audio module, and I have screen freezing in framebuffer.
Any ideas?
Best regards,
Pavel
