lsof was compiled for an older kernel and doesn't work with the one distributed with 5.2: alice[2032]: lsof lsof: WARNING: compiled for Linux release 2.0.34; this is 2.0.36. lsof: kernel symbol address mismatch: get_options get_kernel_syms() value is 0x108d18; /boot/System.map value is 0x108ce0. There were 416 additional mismatches. /boot/System.map and the booted kernel may not be a matched set.
The command still listed open files as it was supposed to but it did generate the reported warning of: lsof: WARNING: compiled for Linux release 2.0.34; this is 2.0.36. This has been assigned to a developer.
Fixed in dist-5.2.1/lsof-4.39-4. However, lsof depends on the kernel version so intimately that you are probably better off just picking up a lsof src rpm and typing "rpm --rebuild lsof*.src.rpm" to build your own version.
