hi james,

fine that someone has hit that bug again, before
it caused data loss in a production environment ;)

are chances really that low? so - this time the
luck was with me :)

>If you want to volunteer, welcome ;)
i`d like to! what "jobs" need to be done? unfortunately 
i`m no coder, so my contributions will not be that "advanced".
but - better contributing a little bit, than contributing 
nothing :D

>as to the current kernels I only run into
>2.4.22-6 -- hostaudio_kern help text
could you point me to this issue?

>2.6.0-test11-1 -- modules don't work
do you refer to the patches in these postings:
http://sourceforge.net/mailarchive/message.php?msg_id=5886687
http://sourceforge.net/mailarchive/message.php?msg_id=6638150
???

>for both I manually apply the patches
could you please point me to that patches? if not in the SF patchtracker,
shouldn`t we put them in? (and also the COW-Patch?)
it also seems that the clock-skew patch
(http://sourceforge.net/mailarchive/message.php?msg_id=2169314)  
needs to be reworked - it doesn`t apply to 2.6-test11 anymore.


regards
roland

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
