    Is this failing on a SAMBA connection?

    >From what I can see in the code, it is a BUG_TRAP on the MSG_PEEK flag being
    set by the time it reaches the tcp code (line 1632 also traps if MSG_TRUNC is
    set, but I think that the trap at 1568 for MSG_PEEK alone is the relevant
    one). SMB, CIF, and NCP are the only network file systems that seem to set
    this flag. Also, if you are running on a Sparc64/Solaris.

    Looks like some sort of weird networking problem in the 2.6 kernel.
