I wish I could use 4.X but I'm afraid too. When I have tried I have a channel dead errors for my sound and nothing can fix that to my = knowledge. Another big issue is that to be perfectly honest I have no idea how I = got FreeBSD 5 to recognize my sound card, in the past I have always seen "No device driver attached" to my sound card. Earlier this week I noticed = all of a sudden it worked, I don't want to loose this, while it is = malfunctioning its farther than it was before. Another interesting observation, today I did a make buildkernel and my = sound worked for the duration of the build, so this IRQ 9 thing seems to fail = as the cause of my problem. Any further thoughts on this issue are greatly appreciated. Thank you = for taking the time to help me with this -----Original Message----- From: Iain Templeton [mailto:iain.templeton@cisra.canon.com.au]=20 Sent: Sunday, May 18, 2003 8:55 PM To: Remington L.

Now that I know somebody else has the = problem, I'm likely to do more about it. I suspect your kernel panic is likely to be the same as mine (which still happens with 5.1-BETA as of a couple of weeks ago). >BUT I have done alittle testing.

This tends to support my idea. If anything sharing irq 9 gets an = interrupt, all the things on irq 9 get a chance to run. This includes the sound = card, so the driver then notices it has interrupts and does stuff with them. Other than trying to get the sound interrupts working (a thing I don't = know how to do) I can't suggest much else. The flood ping is an interesting = idea which I might try, since I have nothing plugged into my network port :-) (I normally use the builtin trackpad thingy which is on psm0, which = isn't irq 9 so that won't work, and trying to watch a DVD whilst wiggling the mouse might give me RSI). Have you tried the laptop with FreeBSD 4.X? I haven't tried mine, but it might do something differently that works (ie not use ACPI). Hmm, it'll=20 probably panic... I should find a spare CD and try it. Iain
