[2.] Full description of the problem/report:
each time some continued write activity occures on an lvm device
consisted of loopback mounted files , a big assertion failure error comes
out and the device becomes unusable . A reboot from the power button / reset
is required since the system is unable to reboot on its own , even in singe
user mode . kjournald and process dealing with the lvm parition are in
uninterruptable sleep and unkillable .
The issue started the moment i converted an ext2 filesystem on the lvm
device to ext3 . First tried with 2.4.17-smp , continued with 2.4.18-ac1 .
Both patched with smbfs-2.4.16-lfs.patch , modified slightly in the
2.4.18 case to apply cleanly .
The lvm device is consisted of 10 loopback mounted files of 23 gbytes ,
which reside on samba mounted shares .
Everything works ok if i mount as ext2 .
[3.] Keywords (i.e., modules, networking, kernel):
lvm 1.0.3 , ext3 , loopback , 2.4.17 smp 2.4.18-ac1 smp
[4.] Kernel version (from /proc/version):
Linux version 2.4.18-ac1 (root@tassadar) (gcc version 2.95.3 20010315
(release)) #2 SMP Tue Feb 26 23:13:44 EET 2002
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
well there is not oops word in the message but looks like one so i decoded
one anyway
they look in the kernel logs like this :
Assertion failure in do_get_write_access() at transaction.c:730: "(((jh2bh(jh))->b_state & (1UL << BH_Uptodate)) != 0)"

[6.] A small shell script or example program which triggers the
problem (if possible)
/usr/bin/wget -r -l inf -nr -nc -b -np -nH ftp://ftp.kernel.org/pub/
on the lvm does the trick for me after say 30 seconds max .
