I think it's an issue with RPC in general:

I was also checking the Urukul 9910 EEPROM (which writes/reads fine), I was trying to communicate with the PC somehow... and got to this basic case which causes the issue:

from artiq.experiment import *

from artiq.coredevice.core import Core

@nac3
class KeyError(EnvExperiment):
    core: KernelInvariant[Core]

    def build(self):
        self.setattr_device("core")

    @rpc
    def yes(self):
        pass

    @kernel
    def run(self):
        self.core.reset()
        self.yes()

Looks like a regression. ARTIQ be3f05a4c0b9ce726dbbe83a7d237d2327725c93 does not have the bug.

The culprit is 94aac16cc5, reverting it works around the problem. Remove -pgo to reduce compilation time.

Seems we're not out of the woods with this one...

from artiq.experiment import *
from artiq.coredevice.core import Core

@nac3
class RPCFail(EnvExperiment):
    core: KernelInvariant[Core]

    def build(self):
        self.setattr_device("core")
       
    @kernel
    def xxx(self):
        pass
    
    @rpc
    def report(self):
        print("OK")

    @kernel
    def run(self):
        self.xxx()
        self.report()

  File "/home/sb/artiq/artiq/language/core.py", line 79, in run_on_core
    self.core.run(fake_method, args, kwargs)
  File "/home/sb/artiq/artiq/coredevice/core.py", line 92, in run
    self.comm.serve(embedding_map, symbolizer)
  File "/home/sb/artiq/artiq/coredevice/comm_kernel.py", line 819, in serve
    self._serve_rpc(embedding_map)
  File "/home/sb/artiq/artiq/coredevice/comm_kernel.py", line 667, in _serve_rpc
    args, kwargs = self._receive_rpc_args(embedding_map)
  File "/home/sb/artiq/artiq/coredevice/comm_kernel.py", line 511, in _receive_rpc_args
    value = self._receive_rpc_value(embedding_map)
  File "/home/sb/artiq/artiq/coredevice/comm_kernel.py", line 504, in _receive_rpc_value

  File "/home/sb/artiq/artiq/language/embedding_map.py", line 57, in retrieve_object
    return self.object_map[key]
KeyError: 1158022160

NB: 1158022160 is 0x45060410 so this looks suspiciously like another core device pointer.
