View Full Version : [all variants] ipw2100 Broken: "ipw2100_verify failed: -5"

Hi, I've filed this as a bug against linux-firmware (https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/408631), but it's not getting any attention, so I thought I'd also pose it as a question:

After I install jaunty on my IBM/Lenovo X31, my wireless network adapter will work for a few hours each boot for the first few weeks. After a few hours it fails with:

$ dmesg | grep 2100
[ 13.327281] ipw2100: Intel(R) PRO/Wireless 2100 Network Driver, git-1.2.2

... (48 lines of this)

[ 8307.176463] ipw2100: eth1: Failed to power on the adapter.
[ 8307.176470] ipw2100: eth1: Failed to start the firmware.

But then after a week or two the "ipw2100_verify failed: -5" happens on boot. If I try to reload the module it fails with "Device not found via register read."

I'm starting to think this is bad hardware - how can I diagnose that?

Thank you.
