OS X Gurus...need assistance...

I got a kernel panic today and was able to reproduce it.

It happens every time I connect to the Netgear beta FTP servers. It mounts the FTP server as a volume and when I try to eject it, the umount process causes a kernel panic.

Anybody heard of this? Should I just ignore it?

I haven't seen a Kernel panic in years.

Have you tried connecting to the FTP server with Transmit, Cyberduck or FileZilla?

[htismaqe]

No, not yet. I wonder if it has something to do with how it's mounting the volume.

FTP is as ancient as time. Is this a cloud service? Are you doing a force umount?

[TribalElder]

I was getting panics and reboots on an older mac book pro

the fix was running the fix permissions deal.

I use FTP every day. Just because a protocol has been around for a long time doesn't make it bad.

Sure, except it's not particularly secure or fast. Would much rather use something like WebDAV or SVN (depending on what exactly you're trying to do).

I work with linux boxes and the only times I see kernel panic is if there are major file system errors or if there are out-of-memory issues and it's digging into swap.

I'm opening an FTP URL in a browser to download a beta firmware.

When you put ftp:// into a browser on OS X, it automatically mounts that FTP share as a volume.

Once I was done, I just right clicked the volume on the desktop and hit "eject" causing the kernel panic.
