[SOLVED] Changing a parameter in /sys/module
Hi folks,
I have installed a Chimaera snapshot with kernel 5.10.24-1 onto my old (but very nice) Lenovo T500. Everything went fine and the system runs quite good.
But (there must be a but): During startup the machine hangs for about 2 minutes with message Firmware: failed to load iwl-debug-yoyo.bin.
However the wifi runs perfect.
I found a hint in the net from a Debian developer that the parameter in /sys/module/iwlwifi/parameters/enable_ini should be changed from Y to N. Ok, I changed the parameter, but after a reboot there is the former value again.
Is there a way to change the parameter permanently?
Regards
Berni

Re: [SOLVED] Changing a parameter in /sys/module
Create a file named /etc/modprobe.d/iwlwifi.conf with content
options enable_ini=NSee man modprobe.d for details.
(That man page belongs to the kmod package, which may and might not be installed)

Thanks Ralph. I created the file and indeed the value now stays at N. However the developers hint was not helpfull and I only get the 2 minutes pause one step later with: cfg80211 failed to load regulatory.db.

Re: [SOLVED] Changing a parameter in /sys/module
On my T420 running chimaera, I get the same message about iwl-debug-yoyo.bin, but there's no boot delay. I don't have any error messages about regulatory.db. That loads ok.
I don't know where to go with this. Just thought I'd add some data points.

Re: [SOLVED] Changing a parameter in /sys/module
Probably I'm on the wrong trip!
At first I got the boot delay with the message failed to load iwl-debug-yoyo.bin. I could fix this with the hint from @ralph.ronnquist.
Netx the boot delay appeared at the message cfg80211 failed to load regulatory.db. I fixed this by installaing the crda packages and setting COUNTRY to DE.
And now I have the boot delay at Waiting for /dev to become fully populated.
What will come next?

Re: [SOLVED] Changing a parameter in /sys/module
There is always a slight delay during "Waiting for /dev to become fully populated", that normally takes a few seconds.

Re: [SOLVED] Changing a parameter in /sys/module
Does the haveged package help? The kernel did suffer with an entropy problem a while back, perhaps it has recurred.

Re: [SOLVED] Changing a parameter in /sys/module
Thanks HoaS, your hint was 100% correct and I was able to solve the problem! Reading the BoottimeEntropyStarvation opened my eyes and brought me to tpm. Indeed the T500 has a tpm chip and it requires randomizing. Disabling the tpm security chip was the solution and my old T500 now boots boot very fast. Thanks again for the help. ; )
