Hi,
Since the last update of eudev, I have to wait three minutes at each boot to get my wlan working
I have this in the dmesg:
| Code: | [ 60.761223] iwlwifi 0000:02:00.0: request for firmware file 'iwlwifi-5000-5.ucode' failed.

I think that I have the correct firmwares:
| Code: | alarig@pikachu ~ $ find /lib64/firmware/ -name iwlwifi-5000-* 2>/dev/null
/lib64/firmware/iwlwifi-5000-5.ucode
/lib64/firmware/iwlwifi-5000-1.ucode
/lib64/firmware/iwlwifi-5000-2.ucode
|
And this is my kernel config about firmware:
| Code: | alarig@pikachu ~ $ grep -i firmware /usr/src/linux/.config
CONFIG_PREVENT_FIRMWARE_BUILD=y
# CONFIG_FIRMWARE_IN_KERNEL is not set
CONFIG_EXTRA_FIRMWARE=""
# Altera FPGA firmware download module
# CONFIG_DRM_LOAD_EDID_FIRMWARE is not set
# CONFIG_FIRMWARE_EDID is not set
# Firmware Drivers
CONFIG_FIRMWARE_MEMMAP=y
# CONFIG_GOOGLE_FIRMWARE is not set
# CONFIG_TEST_FIRMWARE is not set
|
I don’t know what is wrong in my configuration.
Thanks

My driver was set as built-in in the kernel, I changed to a module and it solved my problem.
Thanks for your help  |

I stumbled on this and just wanted to add a bit about the "three minutes" aspect, for others who may find this (it's probably mentioned in one of the linked threads, but seems worth mentioning here).
The long delays are caused by the kernel config CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y. This should *not* be enabled, because the iwlwifi driver tries to load higher-revision firmware (that's not yet in linux-firmware) and if it fails, falls back to the user helper. The problem then is that you probably don't *have* a user helper (udev doesn't any more), so there is a 60-second timeout before the kernel gives up and starts looking for the next blob.
When you disable this config, the driver just loops through the list of firmware revisions by itself, no delays, until it finds a usable one.
Hope this helps someone as it was driving me batty. |

I have the "3 minute" problem with wifi connection as well. I tried to disable CONFIG_FW_LOADER_USER_HELPER_FALLBACK in the kernel as the primary mitigation. But it rendered me no wifi at all.
Kernel:

So it seems like the iwlwifi module tries to load the firmware, but fails to do so. When I check my firmware directories I see:
| Code: | # ls -al /lib64/firmware/

This is strange. The firmware seem to be there.
When I re-enable CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y in the kernel I get a wifi connection, but still with the "3-minute wait"
| Code: | # dmesg | grep iwlwifi

Disabling CONFIG_FW_LOADER_USER_HELPER_FALLBACK in the kernel, as the only mitigatin, does not seem to work. Or have I forgotten something?

OK, I tried other method: To build CONFIG_IWLWIFI=m
I can confirm that this solves the "3 minute problem"
