emergency mode seems like this:
Couldn't get size:0x80000...e
Firmware bug : ACPI...buffer. [mem 0xfed40000-0xfed4087f flags 0x201] vs fed40080 f80



I' used apt upgrade and it automatically update my kernel to 4.15.0-42-generic, then I got this problem, but when I chose my older kernel 4.15.0-29-generic I still got this, pls tell me what should I do?
plus my bios is set to UEFI, whether the security boot is on or off, it's no use.
