Description

Lenovo ThinkPad T520 is hanging almost always on power cord connect/disconnect. Tested with oi_151a7.

Workaround:

# eeprom acpi-user-options=0x8

I believe more Lenovo laptops are affected too.

I just found that after the BIOS update to version 1.41 I am no longer able to reproduce the issue. I'll test the machine for a while without the workaround applied and I'll see how it behaves.
