[BUG] Critical FreeDOS kernel bug | Bugzilla is dead (Users)

> if you provide ... I'll give it a look
Late update:

1. Still have the (rarely occurring) bug as described
2. IIRC have seen cca 2 "suspicious" BUG's in FreeDOS Bugzilla that might match this problem ... regrettably the Bugzilla is dead so I can't check them anymore :crying:
3. More exact results:

- File size 633 MiB
- 5 fragments, fragment breaks at cca 50 MiB (2 breaks just one 4 KiB cluster from each other) and 220 MiB (again 2 breaks just one 4 KiB cluster from each other)
- Affected file area 80 MiB ... 96 MiB exactly 16 MiB - thus bug NOT related to fragmentation
- In affected area, 32 KiB are "lost" at the beginning, the complete (16 MiB - 32 KiB) block "moved back" by 32 KiB, final 96 MiB - 32 KiB to 96 MiB filled with garbage (??? , couldn't determine the origin)
- After 96 MiB file is OK again up to the end
- Always occurs in FreeDOS, never in EDR-DOS, so it must be a FreeDOS kernel bug (but possibly already fixed in some "CVS" - see Bugzilla)

PS: Thanks to all DOSSERS who helped debugging this, most notably Steve :-P
