[Touch-packages] [Bug 1886835] Re: crashes to login screen, uvc related stuff blinks on console
I caught the console message on camera: uvcvideo: Failed to query (GET_INFO) UVC control 15 on unit 1: -32 (exp. 1). Googling around it seems this is a pretty spammy message, perhaps it is unrelated to what is actually happening. I can reproduce this crash putting my system under stress, opening a lot of programs and making it swap. At some point it starts stuttering, then crashes. It happens before the swap space is depleted, about 30% of a 2GB swap partition. It's a ThinkPad X1 laptop with SSD. ** Attachment added: "Screenshot_20200710-153131.png" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1886835/+attachment/5391439/+files/Screenshot_20200710-153131.png -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1886835 Title: crashes to login screen, uvc related stuff blinks on console Status in lightdm package in Ubuntu: New Bug description: I started getting random crashes to login screen, about twice a day.

Also, this is the very last thing I see on dmesg just after relogging: ``` [469698.684830] Bluetooth: hci0: Hardware error 0x0a [469698.694845] Bluetooth: hci0: Retrieving Intel exception info failed (-16) [469698.795777] debugfs: File 'le_min_key_size' in directory 'hci0' already present!
