iwl4965 doesn't work.on T61.
Last modified: 2008-12-11 13:51:09 EST
I'm using a 32-bit Fedora 9 install on the T61, because it was all I had to
hand. I'll try x86_64 when it finishes downloading, in a day or two.
Upon loading iwl4965.ko (with debug=0xfffffff) I get the following:

This takes a few seconds after 'modprobe iwl4965'. During that time, it doesn't
actually seem to have registered on IRQ 17.
Created attachment 312692 [details]
sometimes it fails differently... after a power cycle, it seems to fare a
_little_ better but then still fails.
In the above, NetworkManager does seem to have got an IP with DHCP, but then it
failed before I could do anything else (and I removed the module).
Loading the module again gives me the originally-reported failure mode, which is
also what I get after a reboot from Windows.
Are you still experiencing this issue? I've been using -108 on a t61 w/ iwl4965 quite a bit lately w/o problems.
Yes, although I'm a little inclined to suspect hardware problems. Windows doesn't work after a reboot either. Although Windows _does_ work after a power cycle. Most of the time.
Hm. I just saw this on a completely different machine (MacBookPro), with iwl5300. This is very similar to one of the failure modes I've seen on the T61:
Sep 13 16:58:45 macbook kernel: firmware: requesting iwlwifi-5000-1.ucode
Sep 13 16:58:49 macbook kernel: iwl4965: START_ALIVE timeout after 4000ms.
This happened after a yum update installed kernel-126.96.36.199-29.fc9.x86_64 and iwl5000-firmware-5.4.A.11-2.noarch -- it was working before with kernel-188.8.131.52-108.fc9.x86_64 and iwl5000-firmware-5.4.A.11-2.noarch, and works again after I downgrade them both. I'll downgrade one at a time to check which one was at fault.
Is this an issue with rawhide kernels?
No, rawhide seems to work. 184.108.40.206-79.fc9 still broken on my MacBook though:
iwl4965: START_ALIVE timeout after 4000ms.
Same problem on Dell E6400. Downgrading to http://mirror.unl.edu/fedora/linux/updates/testing/8/i386/iwl5000-firmware-5.4.A.11-2.noarch.rpm didn't work (can this be done with yum? how?), using kernel 220.127.116.11-79.fc9.x86_64. Downgrading to kernel-18.104.22.168-108.fc9.x86_64.rpm didn't help either - same error message about "START_ALIVE timeout after 4000ms.".
