Re: USB ports disabled on Lenovo Thinkpad T61

2016-09-19 Thread Mike Schreckengost
Just for the record, after compiling a new kernel with fresh 6.0-current source 
code
the problem appears to be resolved on my Thinkpad T61.

/usr/ src/sys/dev/usb/usb_subr.c is revision 1.131 now. Thanks Martin, jsg@ for 
the
quick fix.

Yes, I have a similar issue on an X220, but for me it manifests with the
fingerprint reader, a ugen(4) device, and not with two types of umass(4)
devices -- both memory stick and dvd burner work fine.

It appears to me if I revert src/sys/dev/usb/usb_subr.c to r1.128, the
device problem is eliminated, so Martin is in copy for his awareness.
(He may already be aware, of course.)


Same issue, keyboard/mouse doesn't work after upgrading to Sep 18 snapshot. I'm 
not even getting a message in dmesg. It's completely silent.

I was running Sep 7 before that (where it worked). Also on Lenovo (Thinkpad 
T440s).

USB ports disabled on Lenovo Thinkpad T61

2016-09-19 Thread Mike Schreckengost
Hello misc,

Sometime between the OpenBSD-current snapshot released on Sep 10 2016
and the snapshot dated Sep 18 2016, the USB ports on my Lenovo Thinkpad
T61 ceased to function. Upon plugging a device into any of the 3
available ports, I receive messages such as these:

uhub2: device problem, disabling port 2
uhub3: device problem, disabling port 1

Is anyone else experiencing a similar issue? If I can provide any
additional information to help debug this problem (beyond my system
dmesg, which is attached) please let me know. I'd also be happy to test
patches, if necessary.

As always, for the OpenBSD devs: thank you so much for your dedication
to the OpenBSD project. Your efforts are greatly appreciated by myself
and countless others who truly understands the value of a secure,
stable, and funtional OS.

-Mike

Thinkpad T61 Intel video bug?

2014-12-28 Thread Mike Schreckengost
Hello everyone!

I am looking for help trying to track down the source of a problem that
has cropped up in OpenBSD sometime between the 5.6 release and -current.
When doing various things in X, which includes attempting to play a video
inside the chromium web browser, the following error is displayed on the
console:

error: [drm:pid3513:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU 
hung
error: [drm:pid211:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU 
hung
error: [drm:pid14269:i915_reset] *ERROR* GPU hanging too fast, declaring wedged!
error: [drm:pid14269:i915_reset] *ERROR* Failed to reset chip.

After this point, the system can no longer play videos in mplayer, resulting
in a blank screen (sound still works) and these error messages, repeatedly:

X11 error: BadAlloc (insufficient resources for operation)

A:   1.6 V:   1.6 A-V:  0.012 ct:  0.037   0/  0 12%  3%  0.7% 0 0 

Restarting X does not solve the problem. The only solution appears to be a
complete reboot of the system.

As pointed out earlier, OpenBSD 5.6 does not seem to be affected by this
bug. I am willing to test out patches and/or possible workarounds, if anyone
has a clue as to what might be happening here. Complete dmesg and Xorg.0.log
follows.

Thanks in advance for any help. The system in question is a Lenovo Thinkpad
T61, if that information is of any value.

iwn(4) fatal firmware error

2011-07-06 Thread Mike Schreckengost
Hello misc,

I am running an unmodified version of OpenBSD 4.9. The problem that I am
experiencing is in regard to the iwn(4) driver, which occasionally crashes
with a 'fatal firmware error' message. So far, I am unable to nail down any
specific activity (browsing the web, ftp, etc) that triggers the problem, and
could not locate any similar bug reports via Google or the OpenBSD bug
tracking system. I am providing the complete error information as reported by
the driver, along with the dmesg from the affected system. Any help or ideas
would be greatly appreciated. If more information is necessary, please let me
know and I will make every attempt to provide it.

Thanks in advance,
Mike

bsd.mp, different IPL interrupts = degraded performance?

2005-07-15 Thread Mike Schreckengost

Hello all,
   I have recently installed OpenBSD 3.7-current (as of 07/12/05) and have 
selected the bsd.mp kernel since I am running a system with 2 CPUs. After 
looking at the dmesg output after the initial boot, I noticed the following 
strange lines near the bottom:


ioapic0: pin 17 shares different IPL interrupts (40..90), degraded 
performance
ioapic0: pin 18 shares different IPL interrupts (40..50), degraded 
performance
ioapic0: pin 19 shares different IPL interrupts (40..50), degraded 
performance


   I have done google searches, but was unable to determine the cause of 
these messages. Additionally, I have sought help on the #openbsd IRC channel 
(freenode.net) but no one seems to be able to figure out what's going on 
here. The details of my particular system are spelled out in the full dmesg 
output, which is listed below.
   Specifically, I would like to know what the reason for these messages 
might be, whether or not they are anything I should worry about (the system 
is up and running, with no noticeable problems thus far), and if there is 
anything I can do to remedy the situation. As always, thanks in advance for 
your help.


Cheers,
Mike
