After installation of intel_wifi package from depot net_server started to regular crash, but WiFi-networks appeared without ability to connect due to "Bad port ID" error. The removal of intel_wifi package over depot requires to uninstall most of installed (and system too) packages, so only manual uninstallation works. After package removal network monitor shows no available networks again.

The net_server crashes are probably because of marvell_yukon. I think one of my laptops also has net_server crashes and has a marvell_yukon device. Please try to block the marvell_yukon driver in the boot loader, and see if this helps with net_server crashes.

Please also provide a syslog.

[ArmanHayots]

System succesfully ignored my /boot/settings/packages file, so I've to disable marvell_yukon using safe mode and nothing changed. In other hand, removing bv43_cutter package and after then installation of intel_wifi done the work - system now can see wifi-networks without regular net_server crash (at least not too frequently), but unable to connect to any network due to wrong password error. I'm attaching all 3 syslogs - initial, with marvell disabled and current, and packages file too.

[ArmanHayots]

With disabled marvel_yukon all net_server crashes are gone (I tested for near a half of a hour), but wifi still unable to connect, showing «Bad password». wpa_supplicant log the same.

/dev/net/iprowifi4965/0: Failed to attach pkt_type filter

I can't recall seeing this message before; it might be the problem, or it might be harmless. Can you test with beta4 and see what happens?

[waddlesplash]

korli: Any chance you can debug the crashes a bit further? It looks like an invalid BMessage is trying to be converted; that shouldn't crash applications even if the kernel is sending something wrong.

[ArmanHayots]

Will try. Also sometimes system falls in KDL without ability to use it — I can erase all screen using Backspace and not of any printed commands nor shortcuts working. Syslog shows nothing for this situation. Mouse works and sometimes if Deskbar not busy (like in attached screenshot) I can kill net_server and continue to work, but usually only reboot helps.

[waddlesplash]

Are you sure it's KDL and not an app_server crash?

Maybe the marvell_yukon driver is corrupting memory somehow... that would be very bad.

[waddlesplash]

(Or if you've disabled marvell_yukon entirely then that's not the issue.)

[waddlesplash]

Yes, the screenshot looks like the remnants of a Debugger prompt and not a KDL one. You can try typing "save-report" at the prompt, it should save a report onto the Desktop which should be accessible after rebooting.

[ArmanHayots]

"save-report" created nothing. Attaching link to core dump file on net_server crash, hope it helps. Still unable to connect. ​https://disk.yandex.ru/d/HAzqAn9oUnDUYg

Maybe the marvell_yukon driver is corrupting memory somehow... that would be very bad.

Which started only after module installation. More looks like two drivers (Intel and Marvell) fighting for same memory.

Performed fresh install of the latest nightly build (57427). All crashes gone and even WiFi successfully connects out of the box, but no Internet access available — all packets lost. After reboot again attacked with wrong WiFi passwords error (and syslog started to overflow with "wlan()" messages again). Connected back to Ethernet and then updated all packages to the latest and then the problem gone — at least for now. WiFi successfully connecting and WebPositive showing sites. After reboot Wifi password error started again, but after disabling Ethernet device all worked.

What I want to say as offtopic.

1. It's will be good to have a tool or script to restore all bundled packages in the state of newly installed system according to build number — even over Depot.
2. Maybe we should provide some default public DNS addresses — like Google/Yandex/OpenDNS?
3. It's strange that driver packages like intel_firmware, realtek or bw43_cutter on installation trying to drag down with them half of system.
4. Package blocking over /boot/settings/packages and save-report sometimes not works (in my case never did) and I have no clue why.

[ArmanHayots]

*bw43_cutter on uninstallation, I mean

WiFi still working, no net_server crashes observed. I should continue testing and will report on the next week.

[ArmanHayots]

Monday report. Wifi only works when RJ45 disabled via Network manager. And sometimes password error starts to bother again so much that only wpa_supplicant kill or system reboot helps. No net_server crash anymore, but one time system stuck at logo screen (will attach syslog.old, but it can be unrelated). Depot app crashed one time, will attach report too. System updated to rev57434.

[ArmanHayots]

1. System not remebering interface state so I need to disable Marvell device on every start.
2. Sometimes it won't connect to my network and just stuck on "Confiuguring" state so I need to kill wpa_supplicant (with net_server sometimes too), connect to another network and then connect back to mine.

[ArmanHayots]

Updated to hrev57458. Marvell shows in interfaces popup even after disabling but in other hand blacklisting over packages started to work again so I'm just disabled marvell_yukon. Password error became permanent and unavoidable so WiFi not usable again. Syslog full again of "KERN: wlan_control: 9234, 16/17/26/103".

[ArmanHayots]

Able to get to work using manual wpa_supplicant start over Terminal (already started wpa_supplicant must be killed). Will attach both syslog and wpa log.
