File open container (Lucide), FM/2 and drives folder hang opening a unifat fat 16 drive. Fat 32 drives also exibit the hang.

[Gregg Young]

The file open container is the replacement container shipped with ArcaOS. FM/2 traps in fm3dll.dll. The other 2 just hang. I have system dumps for all three. To get the system dumps I had to add a ps2 keyboard since C-A-F10-F10 failed from my usb keyboard implying that the problem takes the usb stack down. Power off is the only option without the ps2 keyboard.

I have included a limited analysis of the dump below. Please let me know if you wish additional analysis or if you want the whole dump where to upload it.

From the FOC hang system dump:

Sorry about the bad formatting above. See attached file.

[Gregg Young]

This is with fat32 built without xfat CS 276

[Gregg Young]

I am not seeing this with CS 277

[Valery V. Sedletski]

Would you like to format it properly by

{{{

?

[Valery V. Sedletski]

What do you mean under "hang"? Hangs what? Only user program, or whole system? It does not react on close button? Lucide with FOC is when opening a file? How could I reproduce this on my system? As I don't see any hang neither in WPS Drives object nor in Larsen Commander. I use FC/2 and I have a very old version on FM/2 which also seems to work fine.

[Gregg Young]

The entire system fails to respond. As indicated above if I am using a USB keyboard I must power off the system to continue. C-A-F10-F10 works from a PS2 keyboard. The file FOC shows drives and directories in the left hand pane up to but not including the UNIFAT drive. I mean r277 where all is working again. I have not tried r280. Will try now. Thanks

[Valery V. Sedletski]

In r277, I disabled the experimental USE_STATIC_BUFS define, which can cause a hang on a semaphore. So, it is a known problem.

If if works with r277, it should work with r280 too. If "entire system fails to respond", then it just hanged in PM (FOC dialog) or WPS folder (Drives object) thread. If I use FC/2, only FC/2 hangs (though, until reboot)

[Gregg Young]

I can not reproduce this in r280. Closing will reopen if it recurs
