It is worse than just simple stack overflow, it is close to an infinite loop.
>From examining the stack trace and the DSDT, it looks like this machine is
falling into an "infinite" loop via the following sequence of events:
A temperature EC event starts the whole thing going.
Linux acpi_ec_gpe_query runs
Invoke _Q81 (temp is falling)
Notify (THRM, 0x80)
Perform thermal_check
Invoke active thermal state handler
Attempt to turn off a fan
Invoke _OFF method for fan
Invoke THRM._SCP
Notify (THRM, 0x81)
The Notify (THRM, 0x81) causes a call to thermal_check (in the Linux thermal
notify handler), and we end up in an infinite loop. (or at least we quickly
spin through this thing enough times that a stack fault occurs before some
event terminates it.)
I think it's a bit early to close this bug.
