Subject: Re: [BUG KERNEL 2.6.20-rc1]  ftp: get or put stops during
 file-transfer

Hi,

I investigated the ftp-file-transfer-stop problem by git-bisect method,
and found this problem was introduced by
"[TCP]: MD5 Signature Option (RFC2385) support" patch.

Mr.YOSHIFUJI san, please fix this problem.
