Public bug reported:
I boot ubuntu from a usb 3.0 thumb drive.
But during boot, booting stops at a busybox prompt.
Output of dmesg | tail says:
22.888260 usb 4-2: reset SuperSpeed USB device number 2 using xhci-hcd
My work-around is to: unplug the usb 3.0 drive, plug it back in, then type exit.
After that, ubuntu boot normally.
Busybox version, stated at busybox prompt, is:
v1.27.2
1) $ lsb_release -rd
Description: Ubuntu 18.04 LTS
Release: 18.04
2) $ dpkg-query -l busybox-initramfs
ii busybox-initra 1:1.27.2-2ub amd64 Standalone shell setup for initra
3) I expect ubuntu to boot from the usb 3.0 drive, without having to use
my work-around described above. It used to work fine on older versions
of ubuntu.
4) Instead booting stops at a busybox prompt as described above.
Here is my PC's model of USB 3.0 adapter:
$ sudo lspci | fgrep -i 'usb 3'
02:00.0 USB controller: Texas Instruments TUSB73x0 SuperSpeed USB 3.0 xHCI Host
Controller (rev 02)
Thanks.
