Re: 4.19 kernel 64 bit support - please report issues here

Wed Sep 04, 2019 9:56 pm

So I was browsing in Hexxeh's repo and saw lots of "kernel: Build 64-bit kernel8.img for testing" so that piqued my curiosity. Is that something that's coming when you guys switch to 5.3 down the road or will 4.19 series actually see a 64-bit build some day? What's the actual target device for testing?

I am using Raspberry pi 3b along with Xbee and Sixfab 3G/4G base sheild. Receiving below error in dmesgs.

ftdi_sio ttyUSB0: failed to get modem status: -32

usb usb1-port1: disabled by hub (EMI?), re-enabling... and also getting this WARN::dwc_otg_hcd_handle_hc_fsm:2462: Unexpected IRQ state on FSM transaction:dev_addr=4 ep=0 fsm=6, hcint=0x00000002



After running some time all ports are disconnected and reassigned to different ports. please let us know the solution to overcome this problem.

Rasbian version: Linux raspberrypi 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/Linux

Has this anything to do with our testing 64bit kernel? If not please start a new thread.
