smb_panic

[Karolin Seeger]

Hi list, hi Jeremy,

I apologize for such a bad report, but I do not have any further
information and cannot reproduce.

I mounted a Samba share (data) using CIFS. Afterwards I was not able to read a
file (SLES10-i386-ISO/SLES-10-x86-CD1.iso) despite UNIX and Samba permission 
allowed it. While trying to access this file, Samba ran into a panic action:

Why did Samba ran into that panic action?

If you need any further information, please feel free to ask!

Thanks in advance!

With kind regards,
