Bootload Errors
I am trying to figure out what is causing this issue. I have 16 RPi4's installed and 2 devices boot to this error "occasionally". When it happens, sometimes I can reboot the Pi and it boots fine. This particular image, I have not been able to reboot it into a functioning OS. Another device, it works sometimes and doesn't work other times after rebooting. I originally had this issue when I added another FAT32 partition to the mix. Removing the partition fixed the issue (although, I did notice the error a couple times beyond this).

i bought around the end of November a new phone that phone battery should have a capacity of 5Ah but now, after a bit more than 1 month of heavy use the battery reports a capacity of 4651mAh, that equals a 7,5% loss! can that be true or is it just displaying a wrong value?

Problems installing wireless drivers
Hello World,
I'm trying to install a netis WF2190 wireless USB adapter to my Raspberry Pi 4b with the 64-bit Raspberry Pi OS installed and it's been a while since I've played with drivers in Linux and I'm having some problems.
When I plug in the adapter and run 'lsusb', I see:
Bus 001 Device 006: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN AdapterWhen I run 'lsmod', I do not see the drivers for it, so I tried installing the vendor-supplied drivers for Ubuntu 16.04 for it, located at https://www.netis-systems.com/Suppory/downloads/dd/1/img/443 but I've run into some errors. When I install per their instructions, I get the following error:
make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/5.15.76-v8+/build M=/home/pi/RTL8812AU_WF2190_WF2561/RTL8812AU_linux_v4.3.20_16317_20160108/driver/rtl8812AU_linux_v4.3.20_16317.20160108 modules make[1]: Entering directory '/usr/src/linux-headers-5.15.76-v8+' Makefile:709: arch/aarch64/Makefile: No such file or directory make[1]: No rule to make target 'arch/aarch64/Makefile'. Stop. make[1]: Leaving directory '/usr/src/linux-headers-5.15.76-v8+' make: [Makefile:1656: modules] Error 2I gather this is because of 'ARCH=aarch64', so I did some searching and manually edited the Makefile to indicate: 'ARCH=arm64' per someone else's recommendation for a similar problem (here: https://github.com/Mange/rtl8192eu-linux-driver/issues/228) but now I am receiving the following error:

Could someone perhaps recommend a different driver package for the 8812au wireless chipset for my OS, or otherwise help me figure out the issue with manually specifying 'ARCH=arm64' with the vendor-supplied drivers? Thank you so much! 🙂
