I've encountered a reproductible 'Assertion failure' in 2.4.17.
It happens on pure vanilla, as well as on sched O1-J0, and also on
2.4.18-pre4.
I'm testing 2.4.18-pre7 in a moment, when compilling is done
(slow machine).
I've a SMB share mounted on /mnt/smb, in which I've got a 1GiB file
with an ext3 fs on it, that I mount on /mnt/loop
I'm able to write a bit of data on it (about a few Mib), and then I
got this Assertion failure:
--8<-- Begin --8<--
Assertion failure in do_get_write_access() at transaction.c:728:

Then the system is almost responsive (switch consoles, exit, etc...).
But when I try to reboot (what I do as soon as I can!), it hangs.
I'm not under X (X running, but I'm under a fb text console, I hate
that much X...).
syslog does not give me any more that the assertion failure.
I have to power it off physically (power cycle) to regain any control.
After reboot, the FS on the loop file seems OK (recovery complete).
Any idea? I'm ready to test anything you might think of. Cause this is
my work machine and I'm in France, don't expect me to be 'interactive'
when posting!
Thank you for your attention.
Regards,
Yann.
