I expect that the short answer is that your
error was not quite like the versions we
saw before, and so until we got more
information about the exact nature of the
error, it was not clear what the error was
This is also likely the reason you did not
find it while searching...
 
I too had thought that the segfault had
been claimed as fixed :(
 
This error also occurs rarely as it only
appears if the block device length is
within 31 bits of the end of the bitmap
page, 0.09% chance and the sizes are
odd from the human point of view.
 
If you want to volunteer, welcome ;)
 
as to the current kernels I only run into
2.4.22-6 -- hostaudio_kern help text
2.6.0-test11-1 -- modules don't work
for both I manually apply the patches
