I updated a nuc w/ amd64 -current (GENERIC.MP) #154 and have more data.  The 
nuc doesn't have a serial port so I extracted[1] dmesg parts from 
/var/log/messages.  Here's a bit of a summary:

Many thanks to rpe@ for this fix. install.sub v1.943 works perfectly with my 
legacy nas and its self-signed cert.

In an ideal world, I'd have a valid certificate for this local nas server...

Thanks.  Unfortunately, I've been spoiled by the continually improving snapshot 
install methods and want to preserve typing "a" once for a new -current.

That would also solve the self signed cert problem.  Since the install 
/etc/ssl/cert.pem is transient, your method wouldn't trigger any /etc/daily 
alarm about a chang in cert.pem.

I hacked a bit on sthen's suggestion but ran into problems testing the https 
part w/ the OpenBSD servers.  I'm currently unable to do a snapshot autoinstall 
from ftp[35] via the latest bsd.rd.

FWIW, here's my weak attempt at sthen's suggestion:

That would totally work for my install problem.

FWIW, instead of running a patched install.sub, "rm /etc/ssl/cert.pem" makes 
the install bypass the https attempt.

Allow install from https server w/ self signed cert

[RD Thrush]

Rather than add load to the OpenBSD snapshot servers, for years I download a 
snapshot to a local netgear nas server.  With the recent https changes, I'm no 
longer able to install from that server.  I've appended a console log of a 
failed install attempt.

Per src/distrib/miniroot/install.sub v1.940, I added the recommended question 
to the response file, ie.
Unable to connect using https. Use http instead = yes

However, the "ftp: SSL write error: certificate verification failed: self 
signed certificate" message causes the install to abort.

Here's the patch I used to account for the self signed certificate:

Thanks, that would work fine.  It may be useful as a note in the upgrade guide
for 6.0 for those (apparently few of us) who have a read-only /usr.

I have nothing but praise for the related security improvement as well as 
countless others that influenced my choice of OpenBSD since 2.6. I have 
upgraded 100s of times with /usr{,/X11R*,/local} as ro in /etc/fstab.  I made 
the 'bugs' report including a diff [1] two weeks ago when I noticed the 
conflict after a -current upgrade.

After no response, I asked again and unintentionally triggered angry responses, 
although 2 good suggestions emerged.

Edgar Pettijohn [2] suggested adding the mount -ur ... commands to 
/etc/rc.local which works but may warrant a note when [3] is created.

Craig Skinner [4] greatly improved my diff. 

I've been managing the read-only /usr partitions since the change w/ a custom 
autoinstall.

Thanks, Chris.  I provided a diff in my original bugs report.  Craig Skinner
enhanced it and I'll update my autoinstall accordingly.

I didn't mention read-only /etc.  Not sure where that came from.

Thanks, Craig.  That is much better than what I proposed [1].  I'll update my

The report is fairly easy to reproduce.  Make the /usr filesystem read-only in 
/etc/fstab, go to single user mode and exit back to multi-user.  I've appended 
a transcript.

It's unfortunate that mounting /usr read-only is now a mis-configuration.

Is loss of read-only /usr permanent?

[RD Thrush]

Since the anti-ROP mechanism in libc [2] was added in late April, -current with 
read-only /usr produces something like the following message:
re-ordering libraries:install: /usr/lib/INS@OPOjn7ck17: Read-only file system

I thought I was following best practice by mounting /usr, /usr/X11R6, and 
/usr/local read-only.  I submitted a bug report and a patch to fix my problem 
[2] but have had no response.

I've attached the boot log from a kernel compiled with both "option DRMDEBUG"
and Mark Kettenis patch.

I have a similar problem which results in a panic (dmesg appended).  This
machine has a radeon (asus 7770) pcie adapter in addition to the integrated
intel hd4000.  The latter adapter seems to elicit the panic.  If I set the bios
to make the hd4000 the primary display, the panic will repeatably occur.

I have also appended pcidump -vxx when the bios primary adapter is *not* set to
the hd4000.

X will run on the radeon adapter in vesa mode.  I can provide the associated
Xorg.0.log.

Xorg triggers panic w/ Intel HD4000 graphics

[RD Thrush]

Using startx as root w/ no Xorg.conf causes -current to panic when using the 
i7-3770 integrated graphics adapter.  I built a debug kernel and sent a sendbug 
report[1] on Sunday.  I've appended a (serial console) excerpt from that 
report.  The panic is easily reproducible.  Is this a known problem?

apcupsd fails when running a kernel without the UQ_BAD_HID quirk entries.

I also noticed 50+ new uhidev entries in the dmesg since the Aug 1 snapshot.
dmesg at end.  I'm reverting to the last snapshot.

I patched the apcupsd package to enable DEBUG and see the following:

I have IBM's ThinkPad Edge E525, AMD A8-3500M based machine.
And I checked this diff fix that problem.

ok or comment?


Thanks, your patch eliminates the 40 second delay.

AMD APU report

[RD Thrush]

I have a system with an asrock a75m-itx motherboard and an amd a6-3500 
processor.  I notice there is a 40 second delay after the 'ahci0 at pci0 dev 17 
...' line.  I also notice there are two 'not configured' items and 4 'unknown 
product' items.


It appears that I have selected a combination that is not yet supported...

How can I help troubleshoot these anomalies?

I've appended dmesgs for amd64 GENERIC and GENERIC.MP as well as a slightly 
older i386 GENERIC.  In addition, I have collected pcidump, biosdecode, 
dmidecode and acpidump results for each of the amd64 boots at [1] and [2] 
respectively.

/etc/daily ROOTBACKUP duid patch

[RD Thrush]

I noticed that ROOTBACKUP stopped working when I converted the /altroot fstab 
entry to a disklabel UID.  The attached patch seems to work for me but I'm sure 
there's a better way.

Shuttle XPC SK21 hangs unless acpimadt is disabled

[RD Thrush]

 This problem first occurred between the Dec 15, 2008 and
the Jan 16, 2009 amd64 snapshots.  Bug reports kernel/6138
and kernel/6164 have been submitted.

The problem still remains, ie. both RAMDISK_CD and GENERIC
hang unless acpimadt is disabled.  With acpimadt disabled,
the system runs ok.  Both amd64 and i386 versions of GENERIC hang.

I have appended a diff from the current amd64 snapshot, ie.
OpenBSD 4.8-beta (GENERIC) #159: Thu Aug  5 21:28:36 MDT 2010
with and without acpimadt disabled.  I have also appended a
dmesg which includes ddb trace & ps during the hang.

Apparently, with acpimadt enabled, interrupts are handled
differently and since wd0 times out, the hang occurs.  I
compiled a kernel yesterday with ACPIDEBUG enabled but am
lost trying to interpret the results[1] and learn more.
[1] 

FWIW, the hanging dmesgs are also at [2] and [3].
[2] 
[3] 

With the recent ACPI changes, perhaps this is related and
someone can help?

Thanks.  Your patch fixes the problem in a better way.

Sorry about the expanded tabs...
