 Greetings,
  Over the years using the xfce4 desktop, I would occasionally receive
 SHM ERROR messages. As they never interfered (so's I could notice), I
 always put off attempting to track the cause down. However, now having
 performed a fairly major upgrade (~1yr since last), The error appears
 to greatly affect KDE4 (used to use kde3) applications I run within
 xfce4. The windows don't re-draw correctly, and I receive additional
 errors,as well:
 ...
 Resource id:  0x0
 X Error: BadDrawable (invalid Pixmap or Window parameter) 9
   Major opcode: 62 (X_CopyArea)
   Resource id:  0x0
 ...
 After much searching, it would appear to be related to the
 kern.ipc.shm* values.

$ cat /usr/ports/x11-toolkits/qt4-gui/pkg-message

Qt paint engine makes common use of shared memory. To avoid MIT-SHM
errors (i.e., blank windows), you probably need to raise shared memory
limits in loader.conf(5). The following should be safe values for the
KDE Plasma Desktop:

kern.ipc.shmall=32768
kern.ipc.shmmni=1024
kern.ipc.shmseg=1024

 Commenting a driver out is almost always a bad idea and should

Well, few weeks prior to -RELEASE can be considered a last step. :)

 If you are impacted by sbp(4) hangs please follow this thread:


  http://lists.freebsd.org/pipermail/freebsd-current/2007-December/081411.html

 And please let me know if a fix explained in this thread works for you.

Thank you, will test it in few days.

Comment out sbp driver from GENERIC

2011-10-17 Thread Alberto Villa
Hello!

It has been reported several times that some motherboards have issues
at boot with sbp driver loaded. To hide the problem, the driver was
removed from GENERIC in 8-STABLE, but it was left in -CURRENT and it
is now going into 9-STABLE. Please, apply the workaround to 9-STABLE
also!

Re: gptzfsboot and RELENG_7

 Several posts made to this list AFTER the zfs v13 MFC to RELENG_7
 indicated that even after that MFC, you still needed gptzfsboot from
 8-CURRENT to be able to boot from a full ZFS system. Is this not the
 case? I have a 7.2-STABLE built on May 30 and I do not have gptzfsboot
 in my /boot, only gptboot. I didn't make any changes to the stock
 Makefiles and used GENERIC kernel config. Do I need to adjust some
 options for gptzfsboot to get built?

no, it's /boot/loader from 8-current which is needed (the one shared on this 
list works perfectly for me)
to build your system with zfs boot support just add LOADER_ZFS_SUPPORT=yes 
to /etc/make.conf

 the result is, when choosing the disk with the zfs boot

 lsdev does not show any ZFS devices.

same here on 7-stable (csupped yesterday)
i've followed the same steps, but i've used gpt as explained in the

 You can find a copy from 8.0-CURRENT and a script that I tested on a USB

replacing /boot/loader with yours did the job

 Which update, what?  I haven't touched the kernel tree in a while, just
 trying to sort it all out with patches here and there.  Are you saying
 the the 2.7.0 intel driver helped?  Or maybe the Xserver or mesa
 updates?

updating intel driver, xserver and drm helped a lot! i've finally
deinstalled intel 2.5.*, and started using (happily) exa instead of
xaa in xorg
