Very interesting; Etch and Sid use nearly the same kernel today, only Sid is one revision newer running 2.6.18.5. (2.6.18-7 = Etch, 2.6.18-8 = Sid)
Can you post your lspci? I'd like to sniff out your hardware.
Unmodified I can get hard lockup when fsck'ing disk or messing around prior to the GUI coming up. Its seems to be only in the init where I get lockup; The other notable think is the reboot does not operate properly. Without noapic, reboot seems to just "REBOOT" rather than properly shutdown processes, sync disks - effectively it crash-reboots.
Have not tested headphone, but sound is fine. I will though with the 2.6.20-rc2-mm1 I am running now when I have a second with it.
Notably the 2.6.20-rc2-mm1 kernel seems to work best unmodified (crashed once on boot), except that when I type 'reboot' it doesn't go through the normal shutdown still, but does the crash-reboot.
As a sidenote on wireless, Interestingly my ndiswrapper worked fine on a Linksys WRT54G, and then in an airport (the former with WEP) but at my home, it does not work with my D-Link DI-624M. Just won't take - bizare. Interestingly, I have intermitent connectivity with the bcm43xx with 2.6.20-rc2-mm1 (agains which Debian ndiswrapper-source does not build currently) - It's a tease with 80% packet loss. Since my windows driver was v4, I used the auto-downloader with bcm43xx-fwcutter, and that got me this suedo-working v3. Need to mess around with the module options or other firmware v3 to see if I can make it work 100% without ndiswrapper.
Also, cpurfreq-info displays nothing; i.e. Frequency scaling is disabled, so power consumption and heat are at max. With the 2.6.18, sensors does not output the temperatures either; k8-temp sensors show values fine with 2.6.19+
I did note that my full charge (cat /proc/acpi/BAT0/info) is 4700 mAh of design capacity 6000mAh. I was thinking of returning my 8-cell battery, but then caught a glimpse of someone with 3800 mAh on theirs in a forum, only to be told that was normal. (I doubt it - so I am curious if any other dv9000 users can post their BAT info).
iommu=off trumps various pci= and apic options for me
Well,
Using the iomm=off and the stock Debian 2.6.18 (Etch/Sid) kernels I am quite pleased. No lockups or freezes; The reboot/shutdown works 100% of the time, and I am even able to use nvidia drivers and xen hypervisor, so now I am running all my other OSes on top of Debian. 2K3 and XP seem fine so far.
Check out this screenshot.
The 2.6.20-rc6 and rc4 kernels have some updates specific to the HP dv9/6/2000z series laptops (bcm43x, audio, bluetooth).
