Yamagi:

My experience is the same as yours, but only with the combination of Legacy 
BIOS and ZFS installation.  UEFI loading of a ZFS filesystem is also a matter 
of seconds.  So is a Legacy/GPT/UFS installation.  I only see this on my i5 
Skylake when I perform a non-UEFI instalation using the ZFS filesystem.  I 
get a rapid boot with both OpenBSD 5.8 and using a MSDOS 6.22 USB floppy.  I 
have seen some patches posted to this list for testing.  I'll report back 
with my results.  I can't use UEFI because this will be a XEN server and UEFI 
support is not in the XEN kernel yet.

Hello,
I've observed the slowness only on the local console, I haven't tested
the seriel console. Put the FreeBSD legcay installation usb stick into
the box, select it as boot device and watch the cursor spinning for
about 10 minutens until the kernel boots. Do the same with an UEFI
installation stick and it's a matter of seconds... 

I've seen this on an Gigabyte GA-Z170XP-SLI with a Core i7 6700k and on
two Supermicro X11SBA-LN4F based machines with Skylake Xeon CPUs. There
are several other reports of slow boot on Skylake CPUs on the net. In
the thread mentioned below some changes in the hardware, the firmware 
or somewhere else were suspected. I didn't even try to debug it,instead
I went with the UEFI loader.

Regards,
Yamagi

Re: UEFI & ZFS

2016-02-14 Thread Yamagi Burmeister 
Hello,
this is a known problem with Intel Skylake CPUs. Legacy boot os dead
slow, UEFI boot is blazing fast. Have a look at this thread, it contains
some more informations:

https://lists.freebsd.org/pipermail/freebsd-current/2015-December/059037.html

As far as I know now one has found / analyzed the root cause of this
until now.

Regard,

when saying ‘slow’, do you see slowness when printing output to the screen?
I mention this, because in the past I saw something similar, and it was a
misconfiguration with the serial console …

UEFI + ZFS i5 Dmesg

2016-02-13 Thread Thomas Laus 
It looks like my reply to the verbose dmesg.boot did not make it to
the list.  I was able to boot the PC from a MSDOS 6.22 floppy using a
USB floppy drive.  I also can load OpenBSD 5.8 on this PC and it boots
normally.

My verbose dmesg.boot:

That is my exact problem.  It takes 4 minutes to get a complete 'beastie'

What sort of timings do you see if its a UFS install?
