Have you verified that this diagnosis is 100% reproducible? I'm sticking to the cross-build compilers provided by kernel.org, this is what I have so far: 14.2.0 does NOT work 10.5.0 does NOT work 10.1.0 does NOT work 9.5.0 works! 8.5.0 works! I've run this in a couple of iterations, on my system, this appears to be 100% consistent. I'm using vanilla kernel source tree 6.12.3 for the tests and the qla1280 scsi driver as an example for the module unload test case. > I'm asking since since I have now performed some compiler tests with older > GCC versions and the SMP bug [1] is not always reproducible for me. > > Changing the GCC version does not make any difference. > > Regarding the network interface rename/rcu_expedited() problem I've > > tried gcc-8.5.0, gcc-9.5.0 and Gentoo 14.2.1_p20241026 p3 same > > results for all three versions, even though the fix is similar, using > > different compiler versions does not fix the issue. > > What about here? Is that 100% reproducible? And did you try bisecting this? It seems consistent also here, but I haven't really tested it enough yet I'll get back to this one again, still working on the module unload case. /Magnus
