r355009 dies with a kernel panic

[Dennis Clarke]

While is it fine that the CI does a bare bones compile I don't know
if anyone actually tries to run it for a period of time.  If r355009
is left running for a few hours ( on QEMU ) it merely dies with a
panic :


panic: deadlres_td_sleep_q: possible deadlock detected for 
0xffffffd04630a560, blocked for 180225 ticks

So is anyone anywhere trying to run FreeBSD on RISC-V at all or just me?
