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):
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
Created attachment 41227 [details]
/var/log/messages and lspci -vv
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.
No feedback, closing.
