Hi, Looks like commit 5c01cdd2d4bc ("kexec_file: allow skipping checksum calculation for some segments") makes next-20160916 stop working for me at least on ARM. I now get "kexec_load failed: Invalid argument error" on loading the new kernel to memory with kexec -l. Reverting the following two commits makes things work for me again: d2bf993afdf1 ("kexec_file: add mechanism to update kexec segments") 5c01cdd2d4bc ("kexec_file: allow skipping checksum calculation for some segments") Regards, Tony 8< ------- kernel: 0xb6b77008 kernel_size: 0x3aa538 MEMORY RANGES 0000000080000000-00000000ffcfffff (0) 00000000fff00000-00000000ffffefff (0) kexec_load: entry = 0x80008000 flags = 0x280000 nr_segments = 2 segment[0].buf = 0xb6b77008 segment[0].bufsz = 0x3aa538 segment[0].mem = 0x80008000 segment[0].memsz = 0x3ab000 segment[1].buf = 0xadf80 segment[1].bufsz = 0x16080 segment[1].mem = 0x81709000 segment[1].memsz = 0x17000 kexec_load failed: Invalid argument entry = 0x80008000 flags = 0x280000 nr_segments = 2 segment[0].buf = 0xb6b77008 segment[0].bufsz = 0x3aa538 segment[0].mem = 0x80008000 segment[0].memsz = 0x3ab000 segment[1].buf = 0xadf80 segment[1].bufsz = 0x16080 segment[1].mem = 0x81709000 segment[1].memsz = 0x17000 Nothing has been loaded! -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
