Re: [openib-general] ib_local_sa workqueue creation crash with ofed 1.2 + sles9sp3

2007-01-23 Thread Steve Wise 
I guess I was all wet...the latest code works with the name
local_sa...

Sorry for the noise...

Steve.

 I cannot explain this.  The BUG_ON() is for (strlen(name)  10).
 local_sa is 8...9 if you count the NUL at the end.  
 
 But I hit that BUG_ON() for rhel4u4 and sles9sp3.  I reduced the name to
 lsa and it loads fine.

Re: [openib-general] ib_local_sa workqueue creation crash with ofed 1.2 + sles9sp3

2007-01-18 Thread Sean Hefty 
Can you see if the call to create_singlethread_workqueue() passes in a string
longer than 8 characters?  If so, try reducing the size of the string.

I've committed a change to the local_sa.c file this morning to avoid this sort
of backport issue, if this is indeed what it is.
