After upgrade from F26 to F27 I'm not able anymore to boot. Neither with F27 nor with the latest two available versions from F26. I always end in the emergency mode, getting the following errors with "journalctl -b -p 3":

..kernel: ACPI Error: Field [TBF3] at bit offset/length 262144/32768 exceeds size of target Buffer (262144 bits) (20170728/dsopcode-23..

..kernel: ACPI Error: Method parse/execution failed _SB.PCI0.GF0.GETB, AEAMLBUFFER_LIMIT (20170728/psparse-550)

..kernel: ACPI Error: Method parse/execution failed _SB.PCI0.GF0.ATRM, AEAMLBUFFER_LIMIT (20170728/psparse-550)

..systemd[1]: Failed to start Switch Root.

How to fix this in emergency mode? Thanks for your help!! Marco

Have you tried disabling ACPI in the BIOS setup? Alternatively, you could try to boot with the option acpi=off.

This link gives more information on ACPI:

Thanks. Found this:

  • Edit /boot/grub/grub.conf

    • Edit the kernel line and add the option acpi=off. Example: kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet acpi=off
    • Restart your system.

But neither sudo / su root / nano or anything similar works in the emergency mode :/# How to edit the grub.conf from emergency mode? Thanks!

Hit e when grub menu shows up, add acpi=off to the kernel command line, ctrl-x for booting with the added parameter.

ACPI error is gone, but still not booting, new errors are: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000 ERROR UNable to locate a BIOS ROM Fatal error during GPU init Memory type 2 has not been initialized

und deshalb wieder emergency mode ....

Danke für jeden Tipp!

Fortunately I backed up my data before so I decided now to try a fresh install of F27, may be faster ...
