Hi, [I'm not sure if that is a crash or mkdumpfile problem] I'm trying to use crash to read a makedumpfile vmcore from 5.3, but I always end up with an error when opening the dump. I'm using the latest github crash crash 7.2.7++ ... crash: page excluded: kernel virtual address: ffffffff82110370 type: "possible" WARNING: cannot read cpu_possible_map crash: page excluded: kernel virtual address: ffffffff82110360 type: "present" WARNING: cannot read cpu_present_map crash: page excluded: kernel virtual address: ffffffff82110368 type: "online" WARNING: cannot read cpu_online_map crash: page excluded: kernel virtual address: ffffffff82110358 type: "active" WARNING: cannot read cpu_active_map crash: page excluded: kernel virtual address: ffffffff82011544 type: "init_uts_ns" crash: page excluded: kernel virtual address: ffffffff82110360 type: "cpu_present_map" crash: page excluded: kernel virtual address: ffffffff82110360 type: "cpu_present_map" WARNING: ORC unwinder: cannot read lookup_num_blocks crash: seek error: kernel virtual address: ffff88822dffb000 type: "memory section root table" The dump is created with the latest makedumpfile release makedumpfile: version 1.6.6 (released on 27 Jun 2019) It complains that it doesn't support the kernel Any ideas? -Andi _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
