In my case grepping dmesg output for EFI string results in: [ 0.000000] EFI v2.10 by American Megatrends [ 0.000000] Kernel-defined memdesc doesn't match the one from EFI!
Followed by bunch of (mem00 through mem188): [ 0.000000] EFI: mem00: type=3, attr=0xf, range=[0x0000000000000000-0x0000000000008000) (0MB) [ 0.000000] EFI: mem01: type=7, attr=0xf, range=[0x0000000000008000-0x0000000000077000) (0MB) [ 0.000000] EFI: mem02: type=4, attr=0xf, range=[0x0000000000077000-0x0000000000078000) (0MB) [ 0.000000] EFI: mem03: type=3, attr=0xf, range=[0x0000000000078000-0x00000000000a0000) (0MB) [ 0.000000] EFI: mem04: type=2, attr=0xf, range=[0x0000000000100000-0x000000000056d000) (4MB) [ 0.000000] EFI: mem05: type=7, attr=0xf, range=[0x000000000056d000-0x0000000001000000) (10MB) etc (through mem188)... I could provide all memXXX lines if needed. Followed by: [ 1.264080] efifb: probing for efifb [ 1.264341] efifb: framebuffer at 0xd9000000, mapped to 0xffffc90012880000, using 1920k, total 1920k [ 1.264343] efifb: mode is 800x600x32, linelength=3200, pages=1 [ 1.264344] efifb: scrolling: redraw [ 1.264345] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0 [ 1.264390] fb0: EFI VGA frame buffer device [ 1.535400] EFI Variables Facility v0.08 2004-May-17 So, I'd guess based on the above output that my Gateway system is indeed EFI based. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721576 Title: [natty] kernel panic on reboot with (U)EFI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/721576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
