I am trying to get ubuntu breezy running on a computer I was just given at work:

Acer TravelMate 4060
Pentium M 730
Intel Graphics Media Accelerator 900

Kernel: 2.6.12-9-386

I was able to browse the web for hours without a problem. However, when I attempted to copy several large files using SCP over my wireless interface (which uses the ipw2200 drivers), the system froze. I then reproduced the error in failsafe mode, which manages to spit some stuff (a call trace?) out when it crashes. The last lines are:

<0>Kernel Panic - Not syncing: fatal exception in interrupt
<6>synaptics: using relaxed packet validation

I posted a picture of the full output here: www . tardis . ed . ac . uk / ~magli / crash.jpg (LQ will not let me put URLs in my post)

After googling, I tried booting with the "pci=noacpi". However, with this option, my wireless card does not even get detected. Dmesg gives the following:

I am currently using a pcmcia card which uses the orinoco drivers, and it is working fine. Is it normal that my internal wireless card does not work if I boot with pci=noacpi? Any suggestions for me?

Thanks a lot.

I'm not sure I understand. You said the system works with the orinoco drivers, but does not work with the ipw2200 drivers? If that's the case, why aren't you sticking with orinoco?

The ipw2200 drivers are for the my internal intel wireless card, which is causing the problems. I am using the orinoco drivers for a PCMCIA card: they are two different wireless cards.
Sorry if that was unclear.

I have an ipw2200 , I sometimes download files of 700Meg, I have no problem.

Also I remember a friend of mine having the same problem with the latest driver for winbloze, strange!
While he was using Emule, he sometimes has a bsod..

What size are you transfering, so that I can check if it works for me?

I was actually copying several files which were around 50 megs each. The computer would freeze at a random point during the copy. It's funny, cause the computer I was copying from is also using the ipw2200 driver, but it has never had a problem. I do not think the problem is with the ipw2200 drivers in alone, but maybe with the drivers/kernel/chipset combination... But then again, I have no idea.

By the way, j'aime bien ton sig. Ca fait longtemps que j'ai pas vue ce filme.

Hi,

First, you should try the latest ipw2200 driver : 1.0.8 and see if the bug remains.

Also you have to know that the ipw2200 driver 1.0.0 (dunno why this version) was integrated by Intel in the 2.6.14 kernel, so you only need to install the firmwares. But this would require a kernel compile which you probably do not want.

Merci pour la sig
