Re: Apollo Lake kernel panic

[Pedro Ramos]

I cannot check it right now, but I am pretty sure I have disabled the C 
states and as well CSM. Also I have upgrade the firmware to the latest.
At the beginning I also had some troubles. The system was crashing at 
different times. Now it is stable. I am running 6.2 -current not Release.

I copied the bsd.mp kernel from a working machine. Here is the dmesg.  I
also disabled C states in BIOS and was able cleanly to halt machine

Re: Apollo Lake kernel panic

[Predrag Punosevac]

I was able to boot machine which crashed with bsd.sp kernel. Please see
message below. That kernel is non-patched kernel as I was running
normally bsd.mp kernel. Also I forgot to say in my previous message that
I didn't mess with C states (BIOS option). I was also using legacy (not
pure UEFI boot) as the the original installation was done on the system 
which didn't support UEFI boot.

Unfortunatelly I got one of those few weeks ago and it is nothing but
the trouble. The first one died but NewEgg sent me the second one. I
don't know where to begin. 

With the default ACPI configuration options

1. Suspend to RAM  enabled  
2. ACPI HPET Table enabled 

one can't clearly shut down 6.2 stable. This is what I got 

www.devio.us/~ppunosevac/kernel-panic-1.jpg

The system was frozen to the point that I could not get crash trace. 
With suspend to RAM and HPET table disabled I could finally do 

shutdown -p now

without crashing kernel.

I see that even on 6.2 current dmesg which was sent bunch of errors in
dmesg

Unfortunatelly at this point my system is trashed so I can't post dmesg
from of 6.2 stable. Namely after trying to start Chrome I got kernel
panic again but I was able this time to trace it 

www.devio.us/~ppunosevac/kernel-panic-2.jpg
 
Now the system hangs on the boot with the message 

entry point at 0x1000158 

My boot device was RAID 1 and I would appreciate if somebody could give
me a suggestion if I can recover the system (I do have the backup for
data). 

Few more things. I could not get X running on my DVI-D 4:3 monitor.
However both VGA output and HDMI were working. HDMI had no problem using
my high definition Panasonic TV. 

If you attach HDD to ASMedia ASM1061 SATA ports (there are 2 of those
and there are two of SATA3 6.0Gb/s Connectors, support NCQ, AHCI and Hot
Plug) S.M.A.R.T. daemon will refuse to start. I have not investigated
this further.

Sound Realtek ALC892 did work as well as Realtek 8111GR Gigabit LAN.
I could not make a use of 1 x PCI Express 2.0 x1 Slot. Note also that
M.2 is only for WiFi not for storage device.

I am not feeling good about this purchase right now. Maybe somebody
could give me some pointers.

Best,
