Hello, I suffer from the same panic - though the stack is different:

panic() at panic+0x43/frame 0xfffffe008e4cc3a0
mmc_acquire_bus() at mmc_acquire_bus+0x439/frame 0xfffffe008e4cc440
mmcsd_flush_cache() at mmcsd_flush_cache+0x68/frame 0xfffffe008e4cc480
mmcsd_close() at mmcsd_close+0x1f/frame 0xfffffe008e4cc4a0
g_disk_access() at g_disk_access+0x238/frame 0xfffffe008e4cc4e0
g_access() at g_access+0x1c0/frame 0xfffffe008e4cc570
g_dev_close() at g_dev_close+0x17a/frame 0xfffffe008e4cc5d0
devfs_close() at devfs_close+0x36f/frame 0xfffffe008e4cc640
VOP_CLOSE_APV() at VOP_CLOSE_APV+0x7a/frame 0xfffffe008e4cc670
vn_close1() at vn_close1+0x138/frame 0xfffffe008e4cc6f0
vn_closefile() at vn_closefile+0x4e/frame 0xfffffe008e4cc770
devfs_close_f() at devfs_close_f+0x2c/frame 0xfffffe008e4cc7a0
_fdrop() at _fdrop+0x29/frame 0xfffffe008e4cc7c0
closef() at closef+0x24a/frame 0xfffffe008e4cc850
closefp() at closefp+0x9e/frame 0xfffffe008e4cc890

I use 10/stable (amd64) (I know it is unsupported now). The platform is Intel
Apollo Lake with eMMC 5.0 controller (no other special patch or configuration).

I can reproduce the panic with some networking activity that, I guess, triggers
some disk activity which I can't characterize for now).

How can I proceed with this issue? Any pointers are highly appreciated! I can
provide further information.
