Bug 71412

Summary: Flash Plugin problems with SMP enabled kernel.
Product: Ports & Packages Reporter: Jacobo Arvelo <unix4all>
Component: Individual Port(s)Assignee: freebsd-ports-bugs (Nobody) <ports-bugs>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: Latest   
Hardware: Any   
OS: Any   

Description Jacobo Arvelo 2004-09-06 00:50:17 UTC 
When Im browsing flash enabled webpages with any mozilla based browser ( I dont know if it is reproducible with Opera or Konqueror) with an SMP enabled kernel the browser freezes when it loads the flash portion of the page, it come to live when I move the cursor over the "flash area" and freezes when I move off the cursor of the area, very strange.

Fix: 

A temporary work-around is running with SMP disabled, with an UP kernel it works well.
How-To-Repeat: Enter any webpage with flash.

I believe this is related to the recent mpsafenet enabling.  Try
setting:

debug.mpsafenet="0"

In /boot/loader.conf (while staying on an SMP kernel) and see if that
helps.  If so, then try applying the most recent patch to
src/sys/kern/uipc_socket.c and see if that corrects the problem with
mpsafenet set back to 1.

Yes, with debug.mpsafenet=3D"0" it works OK ! Where I can find the
patches for uipc_socket.c ? I need upgrade to 6.0-CURRENT ?

I=B4m looking forward for another problem with Nvidia driver and SMP
kernel, the X hangs randomly, but now, with mpsafenet disabled it
works too.

You can get it from CVS:

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/kern/uipc_socket.c.diff?r1=1.211&r2=1.212&f=u

This sounds like the same problem.

I patched uipc_socket.c  to version 1.212 (latest) and now at least
the flash issue is gone and I hope Nvidia issue too, mpsafenet and
mpsafevm turned on.

State Changed
From-To: open->closed

Fix to the kernel was required; it is in -CURRENT and will be MFCed soon.
