The following reply was made to PR misc/33688; it has been noted by GNATS. From: "Ted Mittelstaedt" <tedm@toybox.placo.com> To: "Dark0n3" <darkone@raketti.net>, <freebsd-gnats-submit@freebsd.org>, <ali.sahin@byd.com.tr> Cc: Subject: RE: misc/33688: Downloading some files with ftp hangs the system Date: Sun, 13 Jan 2002 13:08:24 -0800 Hi Dark0n3 and all I'm CC'ing this feedback that was cc'd to me back to GNATS because Dark0n3 is apparently using a non-standard e-mail client that is trashing the subject line, as a result the auto-feedback sorting mechanism of the PR system did not append his feedback, even though he did send it to GNATS. Dark0n3, since your problem is the system is crashing when you transfer large files via the loopback device, and you have checked everything else, I believe the problem you are having is centered on the use of the 3com 3c905 and the xl0 driver. This card has had sporatic reports of problems before (although a crash is unusual) Note that there are 2 versions of this card, the 3c905 and the 3c905B. Allegedly, the plain 905 has a super-small internal card buffer and more bugs. If possible please try removing the 3c905 and replacing it with a different manufacturer's card, or even a 3c905B and recheck the loopback FTP problem. Note that the following feedback is NOT on the submitters sysstem, we still need the feedback from him.
