kernel panic when using loop device on kernel 2.4.3

I have been getting kernel panics on kernel 2.4.3 when using the loop device on a rather regular basis. I get a kernel panic but no oops message. The kernel panic message says Kernel panic: invalid blocksize passed to set_blocksize. I saw that someone else on the list has had these problems as well but I have seen no response. Has a fix for this bug been posted that I have not seen? Is the fix in any current stable or AC kernel? As far as I know I am not using any strange options. The only thing I can think of would be that multiple people are using the loopback device at the same time. This is because the box that is having the problems is a build server for a custom software distro. We use the loopback filesystem to create the boot image. The box is a 4way xeon with 1GB of ram. Are there any known issues with loopback and SMP? Or even loopback and multiple mounts/usage?

ver_linux output attached.

Thanks,
Mike

If some fields are empty or look unusual you may have an old version. Compare to the current minimal requirements in Documentation/Changes.

There was a response, I just didn't have time to look at the problem just yet.

For now, just losetup and don't mount directly -- the previous report had something to do with that, so I'm assuming that's part of the reason at least.

No
