Don't have a brain injury : you can't hold things in your head, however I got x86 right at least this time :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1794922 Title: lubuntu 18.10 x86 (32bit) image fails to load "ehci-pci 0000:00:a.7: dma_direct_map_sg: overflow 0x000000016e3f3000+2048 of device mask ffffffff" repeats Status in linux package in Ubuntu: Confirmed Status in linux package in Debian: Unknown Bug description: -- Background -- Testing the x86 (32bit) ISO image on various machines.

I've manually typed it; so typo's could have been made.

My last test was also long enough ago to be on 4.17 kernel.
