This panic is kernel virtual address mismatch. You need to rewrite the
following to the same values.

<sys/arch/evbarm/include/vmparam.h>
#ifdef KERNEL_BASE_EXT
#define KERNEL_BASE KERNEL_BASE_EXT
#else
#define KERNEL_BASE 0x80000000
#endif

<sys/arch/evbarm/conf/mk.nslu2>
KERNEL_BASE_VIRT=0xc0200000



Add
options KERNEL_BASE_EXT=0xc0000000
to sys/arch/evbarm/conf/std.nslu2

The slug successfully booted, but failed during ifconfig. If it matters,I'm running a 4.99.62 kernel with a 4.99.60 world. Boot output:
