Follow-up Comment #1, bug #55288 (project grub): Hello Grub Devs! Thanks for mighty fine job you are doing with this project!
Would love to buy you guys and girls beer, if you ever come to Dublin, Ireland - feel free to email me about that beer or other beverage of your choice! With that said, I have a bug I would like to report. And before I describe it, I would like to point out, there are a few bug that are just like mine. All of those I strongly suspect are related. There is this one, then that those ones: https://savannah.gnu.org/bugs/?47636 https://savannah.gnu.org/bugs/?37470 I suspect it's to do with how grub handles USB3 host with USB2 devices. I have USB3 external switch.(TP-Link UH720 USB 3.0 Hub) But I believe I have had this issue when i just connected keyboard to my USB3 port on mother board.(for extra power) HyperX is the keyboard(has 2 usb cables one for extra guice for extra USB slot on it and for nice shiny keys on the actual keyboard). long story short, everything but grub works. Bios has no issues. Once I pass by grub, Linux kernel has no issues and Windows on different laptop has no issues with hub and keyboard.(hence why I got it, i got 6 ports used up, more than laptop has, plus i change hub between home pc and work PC, so i can reuse my nice webcam/soundcard/mouse/keyboard/etc) I can do extra tests to isolate issue to either hub or to keyboard (I have second keyboard somewhere in the house). And I suspect its USB1.1 or 2 or whatever the hell it is, with USB3 host controller. Grub reliably hangs the moment count down and rest of non graphic interface is visible. I got non graphical mode. sys-boot/grub Latest version available: 2.04-r1 Latest version installed: 2.04-r1 Gentoo with Linux dimkosPC 5.6.3 #2 SMP PREEMPT Fri Apr 17 20:30:44 IST 2020 x86_64 AMD Ryzen 9 3950X 16-Core Processor AuthenticAMD GNU/Linux I did trick, once POST finished i switch off hub, grub continues, i switch on host and all works, once kernel started booting. when tried to get lsusb -vv i get this a few times: can't get device qualifier: Resource temporarily unavailable I suspect its due to external usb3 hub I am not lazy and would do physical troubleshooting, as its easiest one, but feeling sickly.
