I've stumbled on the following apparent bugs in Kernel 2.4.2.
I'm not sure the best place to post this so I decided
to ask here.
Perhaps this bug is already known.
Is there a place I can look?
I'm under the impression that there is no official
bug tracking database in place for the kernel.
Is this correct?
An ELF file executes with kernel 2.2.14 (RH6.2) but fails to
execute with kernel 2.4.2 (RH7.1).
Bug 1:
"No such file or directory" is reported although the file exists.
If the 2.4 loader dislikes the file content, an appropriate
error message should be provided.
Bug2:
The file fails to execute under Kernel 2.4.2.
The file is quite old.
However, if feasable, old ELF files should continue
working.
I can ftp the ELF file if someone would like to
investigate this further.
With some encouragement and suggestions, I would be
willing to look deeper into these bugs.
I have disk space for another bootable partition.
Detail follows.
Thanks,
Dave
