Comment (by ttcoder):

 Just had a similar KDL (occurs very rarely here), starting from
 BSecureSocket::WaitForData() instead of BSecureSocket::Disconnect() if I

 I say "if I recall" because I don't have the full backtrace: I expected it
 would be in `previous_syslog` but unfortunately the interesting part is
 corrupted/truncated by some trailing 'color codes' themselves followed by
 seemingly random binary garbage:

 write access attempted on write-protected area 0x54 at 0xdeadb000
 vm_page_fault: vm_soft_fault returned error 'Permission denied' on fault
 at 0xdeadbef7, ip 0x8008d6be, write 1, user 0, thread 0xb45
 PANIC: vm_page_fault: unhandled page fault in kernel space at 0xdeadbef7,
 ip 0x8008d6be
