--- Comment #23 from Navin ---
1) First is
Why does these lines get printed in 4.2
[ 0.716610] ahci 0000:00:1f.2: version 3.0
[ 0.716620] ahci 0000:00:1f.2: can't find IRQ for PCI INT B; probably buggy
MP table
where as in 4.4 and 4.6 you don't get to see even the "version 3.0".
In your initramfs shell , you should try to see if ahci is actually loaded in
/proc/modules
2)
One more thing is i see in 4.2 you have this in dmesg
libata version 3.00 loaded.
I hope in 4.6 also you get that message.
You can find it out in your initramfs scripts by doing dmesg | grep -i libata
That should tell you that your modules are not loaded/good because of some
changes or some other reason like corruption?
At the end of initramfs you can do modprobe ahci and see that it prints
lsmod | grep ahci
That should tell you the reason why it is not printing those messages in dmesg.
