Hey all, first time posting here. In the past few months ive started running Solus on one of my laptops and have been loving the ot-of-the-box simplicity of the experience (without all the downsides of Windows 10 or Ubuntu). I hadnt encountered any problems i couldnt easily fix myself based off my experience with other distros but suddenly ive got a weird problem i've never encountered before! I amn't sure when i happened, but all of the USB ports on my Lenovo Yoga 900 which has Solus Gnome installed on it have stopped working suddenly. It was working fine for weeks but the other day i couldnt get my USB mouse to work in any port, nor could i get a USB stick to show up in lsblk. I've done some digging looking for solutions but all i can seem to find is a suggestion to add the "iommu=soft" parameter to GRUB. Of course, Solus no longer uses GRUB and im not exactly familiar with systemd-boot so i have no idea how to do this with that bootloader (if that even is the correct fix) and i cant seem to find info anywhere on how to add that parameter.
Any suggestions that anyone might have for a possible fix would be greatly appreciated! This doesnt exactly make the laptop unusable, but it is a pain in the ass that it has effectively no IO no except wifi and bluetooth!
