SubjectRe: NTFS directory read lockup
Date
An update:

I cannot reproduce the crash if I'm doing the find
only in the NTFS root. If I do it from /, it comes
quite reproducibly (but this is probably only
a coincidence).

Oops - now i see the offsets, ksymoops either
guessed something wrong or the right symbols
are not exported from ntfs (ksymoops says
something similar).

The dumped code snippet is in support.o,
function ntfs_memcpy and the manually
computed call trace (using nm ntfs.o)
approximately (e.g. find_attr does not give
much sense here):

ntfs_memcpy
ntfs_put
ntfs_readwrite_attr
ntfs_decodeuni
ntfs_find_attr
??? (outside ntfs.o)
ntfs_read_attr
ntfs_getdir
??? (outside ntfs.o)
