Bug ID: 234676
Summary: Boot hangs after upgrade to 12.0-RELEASE (acpi?)
Product: Base System
Version: 12.0-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: johanvz...@giantfoo.org
Hardware:
motherboard: MS-7607, sold as Acer Veriton S480G
BIOS: AMI P01-A01 (no EFI)
CPU: Intel Core2 Quad9400 (LGA775)
boot device: SATA-connected SSD, UFS
The S480G manual says:
ACPI specification 1.0b
S0,S1,S2 and S5 sleep state support.
This system was running a GENERIC 11.2-RELEASE kernel without any problems.
I upgraded using the method:
freebsd-update -r 12.0-RELEASE upgrade
freebsd-update install
reboot
freebsd-update install
pkg update
pkg upgrade
reboot
^ After this *second* reboot, the system would not boot -- it hangs before
mounting root; the console messages suggest it's during ACPI-related functions.
(I don't understand why the first reboot didn't also fail -- i believe the new
kernel would have loaded for the first time, then. Perhaps something
significant changed during the second part of the upgrade.)
Disabling ACPI in either the BIOS or in the boot menu causes a (different)
kernel panic at boot.
During a verbose boot, sometimes the last lines are these two lines are
repeated five to seven times:
Table 'FACP' at 0xbdd90200
FACP: Found table at at 0xbdd90200
On other occasions, after the "FACP" lines, these also appear:
acpi0: reservation of ffc00000, 300000 (3) failed
acpi0: reservation of fee00000, 300000 (3) failed
acpi0: reservation of 0, a00000 (3) failed
acpi0: reservation of 100000, bdd00000 (3) failed
I'm going to experiment with some BIOS settings. If those don't help, i'll try
a debug kernel, and then tweaking some kernel settings.
