I recently switched from an ath9k to an ath10k on my (gentoo based)
home-build router, and there is about a two minute delay between the
time of the modprobe of ath10k_pci and the time "iw list" can see the
wireless endpoint. Then there's maybe another delay before the wlan0
device appears in the kernel.
This extreme delay is preventing a normal startup because it causes an
error return in the OpenRC dependency/startup logic.
That dependency tree is it's own problem, of course, but I don't
understand why the delay is taking place. There are no errors shown in
the startup and the system runs fine once manually kicked around to get
it running (e.g. manually modprobing the various devices and then
waiting and then re-triggering various parts of the startup).
I have to reiterate that the system starts and runs fine as-configured
if I put the ath9k device back in, so it's not a system-level
configuration problem.
Is this long delay after module and firmware load some expected effect
that I need to code around or what?
IF the delay is expected, is there some sort of user-space detectable
event that I can use to know the de
I built the device by buying a micro PCI card from SparkLan and a
Chinese PCIexpress adapter card.
The only really weird thing I see is the all-zeros device serial number.
