Description steve kaney 2001-12-22 05:07:46 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3sfk i686)

Description of problem:
See Support ticket #194099.  /var/log/messages shows IRQ 7 detected but
then uses polling.  Expson Photo EX takes 12 minutes to print 1 page. 
Works OK under Windows 2000.  The motherboard is a Tyan Tiger 133 with
firmware upgrade installed.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install Expson Photo EX using printtool
2. Print anything
3.Look at /var/log/messages and /proc/interrupts

Actual Results:  Printer works but is extremely slow (12 minutes/page). 
/var/log/messages shows that IRQ 7 was detected but then uses polling
mode.  /proc/interrupts shows IRQ 7 unused.

Expected Results:  IRQ 7 used.  Printer printing at speeds similar to under
Windows 2000.

The fact that printing is slow is nothing to do with IRQ 7 not being used 
(which is expected behaviour).

Please attach the output of 'dmesg' after you have printed something.
