I was browsing the internet yesterday when my computer has suddenly stopped responding to any interactions, audio was working for a while after that but after that it had stopped working too, the thing I have saw was that I have been disconnected from wi-fi, in logs I saw errors related to wlo-1, it did get disconnected and after that there was null pointer reference bug in kernel
Provide more info with
hwinfo --long | less
I encountered a similar issue. I’m just watching movies, and at one point, the Wi-Fi disappears, and the Wi-Fi icon turns red. I try turning Wi-Fi off and on again, but the system becomes completely unresponsive, leading to a system freeze. The only solution is a hard power-off using the power button."
are you using firefox to watch movies?
No. I’m using Google Chrome
it looks like the problem is back
it doesn’t show anything just few lines like ~
i got help page when i enter this command
Usage: hwinfo [OPTIONS] Probe for hardware. Options: --<HARDWARE_ITEM> This option can be given more than once. Probe for a particular HARDWARE_ITEM. Available hardware items are: all, arch, bios, block, bluetooth, braille, bridge, camera, cdrom, chipcard, cpu, disk, dsl, dvb, fingerprint, floppy, framebuffer, gfxcard, hub, ide, isapnp, isdn, joystick, keyboard, memory, mmc-ctrl, modem, monitor, mouse, netcard, network, nvme, partition, pci, pcmcia, pcmcia-ctrl, pppoe, printer, redasd, reallyall, scanner, scsi, smp, sound, storage-ctrl, sys, tape, tv, uml, usb, usb-ctrl, vbe, wlan, xen, zip --short Show only a summary. Use this option in addition to a hardware probing option. --listmd Normally hwinfo does not report RAID devices. Add this option to see them. --only DEVNAME This option can be given more than once. If you add this option only entries in the device list matching DEVNAME will be shown. Note that you also have to specify --<HARDWARE_ITEM> to trigger any device probing. --save-config SPEC Store config for a particular device below /var/lib/hardware. SPEC can be a device name, an UDI, or 'all'. This option must be given in addition to a hardware probing option. --show-config UDI Show saved config data for a particular device. --map If disk names have changed (e.g. after a kernel update) this prints a list of disk name mappings. Note that you must have used --save-config at some point before for this can work. --debug N Set debug level to N. The debug info is shown only in the log file. If you specify a log file, the debug level is implicitly set to a reasonable value (N is a bitmask of individual flags). --verbose Increase verbosity. Only together with --map. --log FILE Write log info to FILE. Don't forget to also specify --<HARDWARE_ITEM> to trigger any device probing. --dump-db N Dump hardware data base. N is either 0 for the external data base in /var/lib/hardware, or 1 for the internal data base. --version Print libhd version. --help Print usage.
the problem occured once again, and discovered more specifics of the problem, i have been having my laptop in sleep mode, and i woken it up the wifi was down, the lockscreen(gnome-shell, wayland) was working like nothing happen but after logging in the computer stopped responding, so the problem doesn’t crash gnome(wayland) screen lock
It was yasterday
And again(just now)
I updated kernel to 6.4.13-200.fc38.x86_64
And it also occurs on that version
On Last 2 occurrences I was constantly refreshing one page
i found link for the one of two errors abrt analytics
hm, it looks like there were 2 errors in the same time
3 did only occur once so it looks like it’s not related
I found a reason why WiFi disappears and system freeze. The problem is my built in WiFi adapter (MT7921e). It has no drivers for Linux, so it’s the reason in my case
on linuxHardware it shows that newer distros(from around 2020 and up) support it
here’s link for my card on linuxhardware
I found this in logs, the device was disconnected after ieee80211_reconfig failed
WARNING: CPU: 0 PID: 101533 at net/mac80211/util.c:2547 ieee80211_reconfig+0xdd/0x16f0 [mac80211] [mac80211]
iwlwifi 0000:00:14.3: Microcode SW error detected. Restarting 0x0.
that’s the end of one entry in logs,
then as said it started restarting and everything had begun
that doesn’t happen with 2.4Ghz wi-fi
the problem is my wi-fi is 5 ghz and i don’t wanna make it slower. So i’m forced to use 5ghz.
