Boot halts on Thinkpad X220 (Sandy Bridge)

2011-05-15 Thread Johannes Dieterich 
Hello everybody,

on a Thinkpad X220 (Sandy Bridge/Cougar Point based) the installation
medium loads but halts during boot. I tested the following versions of
FreeBSD

* 8.2-RELEASE
* 9-CURRENT (latest official snapshot from 02/2011)
* 9-CURRENT (latest snapshot from Nathan Whitehorn as of 20/04/2011 [1])
* 9-CURRENT (own release medium as of today prepared with the
generate-release script)

With 8.2, I see the same error messages as [2] with PCBSD-8 (not
surprising, of course, but please note that there is no Firewire in this
notebook). I do not see what the error message is with 9.0 before it
halts. Anyway, according to Kris Moore this is a "known issue with
FreeBSD". I have not found anything about such problem in the mailing
list archives (apologies if I am wrong).

Therefore my question simply is, whether this problem is known and (if
yes) there is a fix or workaround available for CURRENT.

If needed, I can post a dmesg of a successful boot of the
openSUSE-11.4-LiveCD as reference (not doing so now because I assume the
list will anyway eat the attachment). Also, I can provide whatever can
be obtained using said Linux.

Thanks a lot or any replies! :-)

Hmm, is this booting amd64 or i386?  Can you try i386 if you haven't?  If i386 
doesn't work at first, you might need to try disabling APIC via 'set 
hint.apic.0.disabled=1' at the loader prompt.

Sorry, forgot to mention it. Machine has 8 GB of RAM so I have been using
amd64 images for all tests. I will try tonight with an i386 snapshot. Would
the one provided by Nathan Whitehorn be recent enough? Anything in
particular that you would be interested in if it should work (verbose dmesg,
...)?

Thanks a lot for the reply!

Yes, a verbose dmesg would be ideal, I just figured it would be hard to get 
that on a laptop for the non-booting case. :)

A verbose dmesg from a working boot would probably be helpful if you can get 
it though.

The i386 image as of 11/04/2011 of Nathan Whitehorn booted into the live
system without problems. The hint was not needed.

Please find a verbose dmesg at http://pastebin.com/4UTHsg7F

Does this tell you anything?

If you (or anybody else) should need anything more, just let me know how
to obtain it! :-)

Yep, my T420 boots the i386 version just fine, so it definitely looks
like an amd64 issue.

Hiya
If it's any help, I tried booting OpenBSD-Current on a ThinkPad X220
yesterday & it worked just fine (I forget to take my copy of 8-STABLE
snapshot which I downloaded from the allbsd site, otherwise I would've
post that too)

(Sorry I can't reply to anyone, I just joined the list.  I saw this 
discussion in the archives and thought I should join in.)


I've managed to boot a X220i using -CURRENT as of last night.  I got some 
help on -questions to get it done though.  From a blank machine, you'll 
need either a non-USB boot device with FreeBSD media (untested) or a USB 
keyboard.  If you are using a USB keyboard


set hint.atkbd.0.disabled=1

to install, and use the USB keyboard during installation.  Then on the 
first reboot in the BIOS set 'USB UEFI BIOS' to disabled.  (This means you 
can't boot from a USB device.)


At that point, the machine will boot fine.  I've tried 8.2-RELEASE, the 
last amd64 -CURRENT I could find on the FreeBSD website, and -CURRENT as of 
2011-05-16.


I'm building a couple of ports at the moment, and want to reboot with a 
couple of config changes in the loader to see if I can get the WiFi 
recognized.  As soon as I do that I can post my dmesg someplace.

Thanks a lot for the very valuable hint! :-) Booting the amd64
installation medium works now, I will report after the install whether
the second part also works for me (but I am pretty sure of it).

Thanks a lot again! :-)

I'm not on a sandy bridge, but a core2 based lenovo thinkpad (SL410, I 
seem to have this thing fully supported finally...f-keys, sd card etc!). 
I've noticed that BTX halts about 60% of the time for me via DVD. My 
keyboard also does not work at login prompt or elsewhere (during 
fsck...faster!) until after about 2-3 keypresses, after which it's fine. 
BTX via CD/DVD actually seems to work better if i start impatiently 
hitting the keyboard when "-" appears.


I'm not sure if this is a related issue. I also had amd64 btx problems 
on a Dell desktop, so it might be a SATA/scsi/cam timeout thing. Never 
had a problem on server hardware, although most of those boxes were 
Opterons (and thus associated chipsets).


I've come to view FreeBSD dvd boots as a form of gambling.

I finally got around to trying is out, and although the installation
completed successfully, the installation isn't recognized upon boot. I
am getting a PXE-E61 error: media test failure, please check cable. I
tried reinstalling three or four times, with the same results.

I do not believe the issue is a BIOS setting or HD failure, because i
can still successfully install windows 7 without any problems.

Re: Boot halts on Thinkpad X220 (Sandy Bridge)

2011-05-27 Thread tiredash...@gmail.com 
It appears this was just a boot loader problem. Using BTX loader
appears to fix the issue.

Well, that's not a perfect fix and we do lose the ability of detecting
typematic rate (by default), so technically it's a workaround
(sufficient to make the kernel boot and work, though) and doesn't fix
anything.

I have committed it anyway since we do not have better fix (yet), and
have updated atkbd(4) manual page so one can enable it again when
wanted.

The problem we had was that it seems that running the BIOS in the
x86emu emulator on amd64 would cause problem.  This doesn't seem to be
fixable without hands-on experiments on a system in question, it's
either a BIOS bug or an emulator bug.  The strange part of the problem
is that the functionality is quite common in the Good Old Days (TM).

Lenovo has posted an updated BIOS for the box.  Would you like me to try

I got BIOS dump from gnn last week.  I've been scratching my head 
cause it should just fail and exit gracefully unless I am totally 
missing something. :-(

Are you guys sure that INT 15h is causing hangs?  Maybe INT 16h is the 
real culprit (which is more probable, BTW)?

BTW, it shouldn't call INT 16h at all unless INT 15h succeeded 
somehow.  So, I am totally lost. :-(

I found something strange about this BIOS (well, if we can call it 
that).  Please try this:

Index: sys/dev/atkbdc/atkbd.c
===
--- sys/dev/atkbdc/atkbd.c  (revision 222550)
+++ sys/dev/atkbdc/atkbd.c  (working copy)
@@ -1100,7 +1100,8 @@ get_typematic(keyboard_t *kbd)
if (!(kbd->kb_config & KB_CONF_PROBE_TYPEMATIC))
return (ENODEV);
 
-   if (x86bios_get_intr(0x15) == 0 || x86bios_get_intr(0x16) == 0)
+   if (x86bios_get_intr(0x15) != 0xf000f859 ||
+   x86bios_get_intr(0x16) != 0xf000e82e)
return (ENODEV);
 
/* Is BIOS system configuration table supported? */

You must re-enable typematic probing from loader to test it, of 
course.  I think the following line should do:

hint.atkbd.0.flags="0x10"

Note: You may add printf() before and after the check to make sure it 
is being called (and it fails immediately).

A long answer goes like this.  INT 0x15 and 0x16 vectors have fixed 
entry points in *real* BIOS, i.e., 0xf000:0xf859 and 0xf000:0xe82e.  
For this BIOS (or CSM), INT 0x16 vector is correct but INT 0x15 
vector is not (0xf000:0xb4f1).  Funny thing is 0xf000:0xf859 actually 
points to a working INT 15h handler, it seems, which confused me 
totally.  Probably it was done like this because (U)EFI CSM spec. 
mandated it to be located @ 0xf000:0xf859.  If we follow the 
interrupt vector (0xf000:0xb4f1), it gets nowhere (or jumps to an 
unknown external interrupt handler).  If we follow the fixed address, 
it will exit gracefully.  So, actually there are two possible 
solutions, i.e., 1) check whether the interrupt vector is modified 
(the above patch), or 2) jump directly to the fixed interrupt entry 
point.  I chose Option #1 because it is very hard to find BIOS 
typematic support these days (as you pointed out).

Sorry for the delay.  I finally got a copy of (U)EFI spec and found
the requirement of fixed entry there.

Option #1 sounds like a good idea to me too (if the "BIOS" can break
one rule, it can also break more).  Could you please commit the change
(maybe revert mine before that?) and merge it back to -STABLE?

Thanks for your time on investigating this!

I think this should be fixed by recent changes to the atkbd driver in HEAD
by Jung-uk Kim.  I'm not sure if there is a newer snapshot built yet, but
perhaps you can try booting a HEAD kernel into single user mode (will probably
blow up due to not liking /sbin/init) on your i386 world (would need to
use a cross-build (so 'make TARGET=amd64 kernel-toolchain; make TARGET=amd64 
buildkernel', etc.) as a test?
