Strange, we have several of these systems, but I can only reproduce it
on only one of them.
On the systems that work, I see:
[ 8.226607] efifb: probing for efifb
[ 8.230224] efifb: No BGRT, not showing boot graphics
[ 8.235277] efifb: framebuffer at 0x881010000000, using 1200k, total 1200k
[ 8.242148] efifb: mode is 640x480x32, linelength=2560, pages=1
[ 8.248063] efifb: scrolling: redraw
[ 8.251631] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0
[ 8.257458] Console: switching to colour frame buffer device 80x30
[ 8.340917] fb0: EFI VGA frame buffer device
[ 8.353028] Serial: 8250/16550 driver, 32 ports, IRQ sharing enabled
On the one that doesn't, I see:
[ 8.357963] efifb: probing for efifb
[ 8.361579] efifb: cannot reserve video memory at 0x10000000
[ 8.367282] efifb: No BGRT, not showing boot graphics
[ 8.372338] efifb: framebuffer at 0x10000000, using 1876k, total 1875k
[ 8.378864] efifb: mode is 800x600x32, linelength=3200, pages=1
[ 8.384783] efifb: scrolling: redraw
[ 8.388356] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0
[ 8.394237] Console: switching to colour frame buffer device 100x37
[ 8.404419] fb0: EFI VGA frame buffer device
[ 8.408744] Unable to handle kernel read from unreadable memory at virtual
address 0000000000000280
Notice that in the good case it is reserving memory at 0x881010000000,
the bad case at 0x10000000. This reminds me of LP: #1755304. Can you try
updating your firmware?
Your console.log shows you are running:
DMI: GIGABYTE R120-T33/MT30-GS1, BIOS T45 06/14/2017
A working one on my end shows:
DMI: GIGABYTE R120-T30-V6-A/MT30-GS3-V6, BIOS F02 08/06/2019
