https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227116 --- Comment #9 from Daniel Kolesa <daniel@octaforge.org> --- Actually, I managed to obtain a kernel-dbg.txz of the same snapshot and kgd= b it on my server, which runs HardenedBSD 11-STABLE. This is the output: (kgdb) list *uma_startup_count+0xe6 0xffffffff80e13296 is in uma_startup_count (/usr/src/sys/vm/uma_core.c:1827= ). 1822=20=20=20=20 1823 bucket_init(); 1824=20=20=20=20 1825 booted =3D UMA_STARTUP; 1826=20=20=20=20 1827 #ifdef UMA_DEBUG 1828 printf("UMA startup complete.\n"); 1829 #endif 1830 } 1831=20=20=20=20 The printed lines appear to be wrong. The actual line (1827) though appears correct, it's consistent with what I guessed from my disassembly. 1827 pages +=3D howmany(zones, 1828 UMA_SLAB_SPACE / roundup2(zsize, UMA_BOOT_ALIGN)); Sadly, without a dump, it won't be possible inspect the memory, and I reali= zed I cannot obtain a crash dump as the kernel panic happens immediately after = it's loaded, before userspace and therefore before any swap/dump device could be= set up. --=20 You are receiving this mail because: You are the assignee for the bug.=
