idualwifi7260 KDL when booting image from USB drive

[vidrep]

hrev56202 x86_64

When attempting to boot the current Haiku image from a USB drive goes into KDL

Updating to the current hrev from SoftwareUpdater and rebooting works OK

(The photo of the KDL actually comes from a test with hrev56208.)

mbrumbelow reports the same phenomenon under the iaxwifi200 driver. Very strange.

I was able to reproduce the issue with idualwifi7260 and iaxwifi200. This was Booting from USB stick with hrev56202 iso.

The crash appears to be due to ic->ic_bss being NULL. That should never be the case in this path, because it is set by ieee80211_media_init before ieee80211_media_status is invoked. So, something is going deeply wrong.

The crash before hrev56208 was committed appeared to be an invalid memory access in tq_handle_thread. That may be related, possibly something is misusing memory.

Please test booting with SMP disabled and see if that makes any differences.

You should be able to work around this, if I am correct, by temporarily blocklisting the driver, upgrading the intel_wifi_firmwares and wpa_supplicant package, and then rebooting; the driver should then work and not crash.
