Hi,

I'm running 11.0-CURRENT r290335 on EdgeRouter Lite,
sometimes it just reboots with panic: kernel stack overflow

panic: kernel stack overflow - trapframe at 0xffffffff8096feb0
cpuid = 0
Uptime: 4h3m29s
Automatic reboot in 15 seconds - press a key on the console to abort
Rebooting...

Then I tried the patches from here
https://lists.freebsd.org/pipermail/freebsd-mips/2014-May/003534.html

The kernel can't boot when I enabled options KSTACK_LARGE_PAGE

ugen0.1: <Cavium Networks> at usbus0
uhub0: <Cavium Networks OCTUSB Root HUB, class 9/0, rev 2.00/1.00,
addr 1> on usbus0
uhub0: 1 port with 1 removable, self powered
random: harvesting attach, 8 bytes (4 bits) from uhub0
Root mount waiting for: usbus0
timeout stopping cpus
panic: MCHECK

cpuid = 0
Uptime: 3s
Rebooting...

Any help would be appreicated.
