(my apologies if this is a duplicate. Verizon has been losing or delaying
my mail, and refuses to address the problem until I switch from
mutt (or telnet to port 25) to Outlook Express.)
My kernel, on an Athlon XP system:
Linux version 2.6.21.1 ([email protected])
(gcc version 4.1.1) #1 Sun Apr 29 16:13:06 EDT 2007
This is repeatable 2 out of 2 times, during boot. It did not happen in
2.6.20-mm2.
The BUG (apologies for the linewrapping):
-------------------------------------------------------------------
