Comment 62 for bug 89746

I've been following this thread for a long time now and although I am not an expert I wanted to share a relative success I've had in order to boot without the noapic option.

This is part of the message to Leann Ogasawara in the thread https://bugs.launchpad.net/ubuntu/+source/linux/+bug/160718

I wanted to share it with you guys in hope it might work for you too. I'm very thankful to you all for this thread, and felt I owed you something. Best of luck

----------------------------------------------------------------------------------------------------------------------------------------------------------------------

I've been partially successful in booting without the noapic option using the newer kernel 2.6.24

My system is a rare HP dv9343eu (Basically an AMD Turion X2 Broadcomm 4312 wireless card (as detected by linux))

While on Feisty or Gutsy (using 2.6.22) I had to specify noapic noirqdebug in order to get a somewhat stable system. That is the combination that best worked for me, because it booted and gave me USB support [although I don't really know whether it was USB 2.0]

Anyhow, I followed your tip and adventured myself into upgrading the kernel manually to linux-image-2.6.24-3-generic (instead of linux-image-2.6.24-1-generic you suggested). At fisrt that made no difference for me, so I decided to make sure and proceeded to install Hardy through a " update-manager -d". I must point out that before proceeding I had uninstalled bcm43xx-fwcutter and the bcm43xx firmware from the restricted firmware manager.

When I rebooted I was glad to see that even though it took considerably a longer time (precisely there was a very long idle time when loading Hardware drivers) it managed to boot up fine!.

I got a message telling me that my wlan card (detected this time as a Bcm4311) was not properly configured and that I needed to install the v.4 firmware for the b43 cards. So I went ahead and did that. First using the Restricted Manager (which installed a non-working bcm43xx-fwcutter) and then manually installing the b43-fwcutter which correctly enabled my wlan and even allowed me join a wireless network without needing ndiswrapper, wcid, etc...

Problem is that when I rebooted the comp, it once again refused to boot properly.

In Conclusion:

I am finally able to boot withouth noapic using 2.6.24 if I don't have any firmware installed for my wireless card. Other things such as suspend/resume/etc still don't work. I still have to try USB, but CPU Freqs seem fine....

Please let me know how I could provide you guys with more ideal information. I so want this to work that I am keen on trying whatever it takes to fix it..
