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: iwl4965: Intel(R) Wireless Wifi Link 4965AGN driver for Linux, version 1.2.26kds iwl4965: Copyright(c) 2003-2008 Intel Corporation ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 17 PCI: Setting latency timer of device 0000:03:00.0 to 64 ieee80211 phy1: U iwl4965_pci_probe pci_resource_len = 0x00002000 ieee80211 phy1: U iwl4965_pci_probe pci_resource_base = f8f44000 iwl4965: Detected Intel Wireless Wifi Linux 4965AGN REV=0x4 ieee80211 phy1: U __iwl_set_bit set_bit(0x00000100, 0x20000000) = 0x27000200 ieee80211 phy1: U __iwl_set_bit set_bit(0x00000024, 0x00000004) = 0x080033D4 ieee80211 phy1: U __iwl_poll_bit poll_bit(0x00000024, 0x00000001, 0x00000001) - timeout- drivers/net/wireless/iwlwifi/iwl-4965.c 501 ieee80211 phy1: U iwl4965_apm_init Failed to init the card ieee80211 phy1: U iwl4965_pci_probe Failed to init APMG ACPI: PCI interrupt for device 0000:03:00.0 disabled iwl4965: probe of 0000:03:00.0 failed with error -110 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] dmesg 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-2.6.26.3-29.fc9.x86_64 and iwl5000-firmware-5.4.A.11-2.noarch -- it was working before with kernel-2.6.25.14-108.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. 2.6.26.6-79.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 2.6.26.6-79.fc9.x86_64. Downgrading to kernel-2.6.25.14-108.fc9.x86_64.rpm didn't help either - same error message about "START_ALIVE timeout after 4000ms.".
