[Kernel-packages] [Bug 1766076] Re: USB over thunderbolt turns off every once in a while

My keyboard just dropped out after a few hours with `5.10.0-1008-oem` build. It's working again after the unbind/bind sequence from above. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

I'm pretty confident I'm experiencing this same issue with a TB16 on "Dell Inc. XPS 15 7590/0VYV0G, BIOS 1.9.1 12/14/2020" 1. I'm able to reset my USB without unplugging/plugging with a "fix_usb" script which does: echo -n ":3a:00.0" | sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind echo -n

Yes, you're correct. Updated snippet: tee /lib/systemd/system-sleep/rfkill-bluetooth-workaround

This is a workaround to make sure Wifi works on each and every resume, not just every other one (obviously this disables wake from Bluetooth) - after "sudo -s". tee /lib/systemd/systemd-sleep/rfkill-bluetooth-workaround

Tried the kernel in #50 and seeing better stability. Still seeing firmware crashes. But recovery seems to work and wifi restored: [ 4064.530572] ath10k_pci :02:00.0: firmware crashed! (guid 96a14669-a82f-4941-a3b3-690b13b81df9) [ 4064.530628] ath10k_pci :02:00.0: qca6174 hw3.2 target
