Thanks Takashi, I appreciate your help so far. I would normally agree with you that it is a BIOS issue, however, the machine is a dualboot with WinXP, where the mute LED works properly after a resume. Do you have any other suggestions on where the issue may be? I hate to keep bugging the list for such a small issue, but I'm not familiar with the code at all. When I get more free time, I'll try to trace through the resume path to see if I can find anything. How does the driver actually toggle the LED? Is the register a physical register on the card that the hardware reads? Or does the code do something else to toggle the LED?

0:02 = 9e1e

0:26 = 800f
After resume: diff regs_w-quirk_after_resume.txt regs_w-quirk_after_resume+mute.txt 2c2

0:26 = 800f
So it looks as if the registers are all ok after a resume, but the LED
doesn't
turn back on.
Then I'd say it's rather a BIOS problem.
