the chances are pretty good. Visiting a flash site is not a guarantee for
Sadly, when I "reboot 0x104"ed, I got a recursive panic.
Here's the backtrace of the original panic:
panic: kernel diagnostic assertion "anon != NULL && anon->an_ref !=
failed: file "/archive/cvs/src/sys/uvm/uvm_amap.c", line 718
fatal breakpoint trap in supervisor mode
trap type 1 code 0 rip ... cs 8 rflags 246 cr2 ... cpl
Stopped in pid 765.5103 (xulrunner-bin) at netbsd:breakpoint+0x5: leave
The next panic looked like this:
uvm_fault -> e
fatal page fault in supervisor mode
trap type 6 code 0 rip ... cs 8 rflags 10246 cr2 b8 cpl 8 rsp ...
kernel: page fault trap, code = 0
Faulted in DDB, continuing...
