So if you don't boot with "acpi_enforce_resources=lax"and you don't load it87 module, do you still have issues with stability?

[ 4.419823] it87: Found IT8622E chip at 0xa40, revision 1
[ 4.419852] ACPI Warning: SystemIO range 0x0000000000000A45-0x0000000000000A46 conflicts with OpRegion 0x0000000000000A45-0x0000000000000A46 (\GSA1.SIO1) (20190816/utaddress-204)
[ 4.419856] ACPI: This conflict may cause random problems and system instability

[Martin Gerdzhev (mgerdzhev)]

Still freezes periodically. Removed "acpi_enforce_resources=lax", removed it87 module.
Just tested it again and it froze after a few hours.

[Kai-Heng Feng (kaihengfeng)]

Does change the BIOS option to "Typical Idle Current" help?

[Martin Gerdzhev (mgerdzhev)]

Well it looks like I already had it set to that. So I guess it didn't help.

[Kai-Heng Feng (kaihengfeng)]

Well, please try the "F20b" BIOS for this board.

[Martin Gerdzhev (mgerdzhev)]

Thanks I was just thinking about the same thing. I just updated to "f20b". Was on F11 until now. I will report if the issues still persist.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Martin Gerdzhev (mgerdzhev)]

I tried the new bios, but still having similar random freezes. Maybe not as many but once every few days it will still happen.
