[Kernel-packages] [Bug 1794922] Re: 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
Thanks Chris for your reply, but my machine is x86 :-(
I will try with other distro. :-(

Title:
lubuntu 18.10 x86 (32bit) image fails to load "ehci-pci :00:a.7:
dma_direct_map_sg: overflow 0x00016e3f3000+2048 of device mask
" repeats
Status in linux package in Ubuntu:
Confirmed
Status in linux package in Debian:
Fix Released
Bug description:
-- Background --
Testing the x86 (32bit) ISO image on various machines.
After zsync download, the thumb-drive is tested ("check disk for
defects") & passes; and worked fine on two systems today (dell d610 &
hp dx6120), however
-- Issue --
dell 755 (desktop) & hp dc7700 (small form factor) it just sits at
lubuntu plymouth screen.
switching to messages, it's just the following repeating
// on dell 755
"ehci-pci :00:1a.7: dma_direct_map_sg: overflow 0x00016e3f3000+2048
of device mask "
// on hp dc7700
"ehci-pci :00:1a.7: dma_direct_map_sg: overflow 0x000162317000+2048
of device mask "
NOTE: I can't copy/paste from systems, as it never completes boot; I
left it >30mins (on 755) & it just kept repeating message. I've
manually typed it; so typo's could have been made.
A discussion on #lubuntu-devel provided a possible cause (Thank you
Walter!) -

seems like it's a usb issue of some kind with 4.18

This fits because whilst I do my testing mostly on d610 & t43 (no
issues today), I'd tested Lubuntu 18.10 before on the dell 755 with no
issues. My last test was also long enough ago to be on 4.17 kernel
(suspicion)

Hi,
I'm with the same error and I don't understand the solution. Will be fixed only
in the next release? There is some steps to run the live image (in my physical
notebook, not emulated)?
Thanks!
