Using trunk 3394, I encountered the FsIoNotify assert while attempting to browse the directory tree in chdkptp GUI on D10

ASSERT!! FsIoNotify.c Line 451
Occured Time  2014:03:29 16:05:07
Task ID: 12714009
Task name: PhySw
SP: 0x00309934

Haven't looked in detail but I would guess it involves the directory listing functions. The file browser also uses stat, but IIRC that was safe.

Me too (r3404) on a3200 (>2000 pictures on card) and ixus115 (~100-200 files). It actually makes the chdkptp GUI almost unusable for browsing and uploading.

Yup, verified in D10 disassembly that OpenFastDir and closedir use the Open and Close respectively.

trunk changeset 3409 protects them with fileio_semaphore
