Hello, i have some further datapoints to the bugs in the fs code that several
persons have been bitten by.
I have a new panic that is also shared by another person. Mr Ian Dowse identified that the rellocation code was in the code path of the crash. I've since then tried to run with the rellocation code turned off.
Instead of the "ffs_clusteralloc: map mismatch" i now get this panic message
"panic: ffs_blkfree: freeing free frag" it would seem that the bug is somewhere else than the rellocation code.
Here is some info from the crash dump (available on request, together with the older one). Hopefully it will help someone and hopefully someone will look into it, please?
Oh yeah, i'm running STABLE as of 2000-08-15.
