Hi all,
 
I would like to report 2 strange reboots after crashs.
 
The first one happened when I was testing wi-fi link by this command "ping
-f -c 1000000 -s 1472 10.40.192.54", approximately 3 minutes latter a
sub-window of the PuTTY appeared with the following message "Out of memory
space" and the console dropped ... panic ... reboot.
 
This is from my output dmesg -a:
 
ath0: stuck beacon; resetting (bmiss count 4)
 

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0xc
fault code              = supervisor read, page not present
instruction pointer     = 0x20:0xc05c3926
stack pointer           = 0x28:0xd14aea70
frame pointer           = 0x28:0xd14aea88
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 52380 (sshd)
trap number             = 12
panic: page fault
Uptime: 16h46m46s
Dumping 255 MB (2 chunks)
  chunk 0: 1MB (159 pages) ... ok
  chunk 1: 255MB (65276 pages) 240 224 208 192 176 160 144 128 112 96 80 64

If anybody is interested in it, I have a complete dump file.
 
 
I have another problem with intentional restarting in the same remote
machine.
 
This crash has occured for the third time today.
 
Again I have a complete dump file to this crash, if it is interesting.
 
I guess that this fault with vr0 device may be connected with LOR´s, which I
reported half a year ago.
