Thanks for digging into this! Looking at diffs between the versions above, I think the problem may be related to the changes in the handling of mem_id, lib_mem_id, and comp->mem_id in hal_init and elsewhere. No smoking gun yet, but I had previously ignored these changes, as it looked to me like the comp->mem_id was something added by bitmuster for their shared memory area tests since it didn't exist in the linuxcnc 2.5 codebase. Looking at the linuxcnc diff from 2.5.0-pre0 to 2.5.0-pre1, however, I see that this is a linuxcnc change and did not come from bitmuster. I suspect something in the preempt-rt patches needs to be updated or tweaked to account for this change, but I still don't understand the code well enough to pinpoint what might need fixing. - -- Charles Steinkuehler char...@steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk+ZfDYACgkQLywbqEHdNFwX9gCeJXuvLLocqO5aBiu0bDjNiRO6 HsIAoPzNwVxCYNyVlGen+5HWXXr9cUzu =Nsof -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
