Description ken larue 2005-09-15 05:46:17 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.4) Gecko/20041214

Description of problem:
The kernel (Red Hat Advanced Server 3.0)crashes at the following:

The code which seemed to be causing the issue
was modified to use mod_timer instead of add_timer,
yet the problem persists. It seems like when 2 print jobs are send at the same time, one of the opens response ACK.

Version-Release number of selected component (if applicable):
2.4.21-4.ELsmp

How reproducible:
Always

Steps to Reproduce:
When printing to one usb printer it is fine, but if they hook up a 
usb printer to a Sun Ray 1g and then on another Sun Ray 1g have 
another usb printer (could be same type of printer have tried 
sveral but did not make a difference) and then from Star Office or 
any other application you try to print at the same time then you 
get the bellow error. They have applied the SRSS 3.0 patch 
119836-01 but have an effect. They did try this with Solaris 10 and 
SRSS 3.1 and did not see the problem. They did see the problem with 
SRSS 3.1 and Lunix.
