Hi!

I'm not sure if this is even something I should report, but better safe
than sorry, yes?
Yes, and there's even a page to compare your LOR against other ones:
http://sources.zabbadoz.net/freebsd/lor.html
Can you try if you find your LOR there ? If not, can you add it
to that page ?
No he can’t and I haven’t in years either. Searching bugs might however be a
good idea; there is a LOR category or tag somewhere.
/bz
Thank you for the replies.
I'm getting these LORs pretty frequently. Is this a normal occurrence
for 11-CURRENT or is it only me having this problem?
Thanks
