B) the huge file duplication and diff/cmp test failures? C) both? D) even more? For (A) I'd not conclude much until results are in for FreeBSD that is head -r365918 or later. It might be a fixed problem. For (B), I've been reporting examples of the issue since 2020-Jun-21 using rpi4-uefi-devel v1.16 and head -r360311 . But my most recent reports are based on the modern dtb that has 3 GiByte for the size of the range (uefi v1.20 and its bundled RPI4B materials or newer raspberry pi materials) and head -r365932. So both old and new got the same type of failures. (I've not tested materials from prior to 2020-Jun-21 with > 3072 MiByte in this way: that is when I discovered the test.) Does that answer your question? === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arm To unsubscribe, send any mail to "[email protected]"
