    SubjectRe: Kernel Oops at tty_buffer_request_room when using pppd program (2.6.37-rc4)
    Date
    Hi All:
    I have tested 2.6.37-rc5 and the bug still exist.
    I also tested 2.6.32.24, the oops frequency is much lower than 2.6.37. (Only
    happened 2 times in one week).

    Regards,
    Baoyb
