Hi there,
I have been seeing some very odd behavior on 4.2-current recently.
I use hotplug. My workstation at work frequently reboots upon insertion of a
usb stick. This may be an electronic fault, but my main workstation at home
(same hardware exactly), can panic like so:
---8<---
cd /mnt/hot/sd0
mkdir mo
uvm_fault(0xd07a2040, 0xf2e7b000, 0, 1) -> e
kernel: page fault trap, code=0
Stopped at updatefats+0x3c testl %eax,0(%esi,%edx,4)
ddb>
---8<---
Unfortunatley the ddb prompt does not respond to my USB keyboard. It seems
to be repeatable, so I will dig around for a serial line or ps2 keyboard if
I don't hear anything back before sunday (when I have time). Hopefully then
I can get a backtrace.
Dmesg follows (with USB stick inserted):
