Hello,
 
The other unusual thing I observed while testing 2.18.0 on 2.6.9
were the following messages in the syslog:
 
 
..kernel: lis_down(sem=f4529108 head/head.c 3350) uninitialized semaphore
 
This is in the lis_strrsrv(q) - stream head read service procedure:
 
     err = lis_lockq(q) ;
 
 
..kernel: lis_down(sem=f5a36508  head/stream.c 263) uninitialized semaphore
 
This one is in queuerun():
 
    if (lis_lockq(q) < 0)
 
 
That is usually seen during application startup when it opens a lot of stream devices.
 
It looks like service functions for particular queue may kick in prior to the queue semaphore
being completly initialized.
This is intermitent(sp?), i.e. it does not happen every time, but pretty often.
 
I'm curious if anybody observed the same messages in syslog?
Is it known problem?

Brian, please keep us posted on that one.
Time permitting I'd certainly give it a try.
