Was you unmounting some storages like sdcard or USB-flash ?
Or something related to namespaces ?
Weird error never seen before.
Code:
<3>As EXT4-fs error, printing data in hex
<3> [partition info] s_id : sda19, start sector# : 10374144
<3> dump block# : 0, start offset(byte) : 0
<3> length(byte) : 4096, data_to_dump 0xffffffc8562f0000
What is sda19 ? check it with "mount" command.
Maybe a broken sdcard or USB-flash ?
Anyway, latest kernel is still unstable, i got also one reboot.
But with different reason compared to your 2 logs.
And therefore uploaded a new test kernel 2021.12.07:
S8
S8+
Disabled RBIN driver. I think it's buggy.
If it works stable without it, then i'll try to fix it, because loosing 228 MB RAM is somehow painful.
