https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233863 --- Comment #29 from Mark Millard <marklmi26-fbsd@yahoo.com> --- Created attachment 203980 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D203980&action= =3Dedit Investigatory /sys/powerpc/aim/trap_subr32.S patch This has avoided getting some Machine Checks instead of Data Storage Interrupts in the MPC750 iMac G4 PowerMac4,1. Of itself it does not make the iMac G3 example usable. The PowerPC docuemntation indicates the MPC750 need for an isync after an mtsr. I also found a reference for needing one after mtmsr for the PSL_EE case. These are special to the MPC750's instead of architectural for 32-bit. There is other code around with mtsr and mtmsr with PDL_EE involved that used isync's. It looks like these were just missed. --=20 You are receiving this mail because: You are the assignee for the bug.=
