Have you checked whether the problem is in the SD card or in the USB flash? Try running cat /mnt/flash/large_file > /dev/null, if it triggers a reboot too.

3

you are right cat also caused turris to reboot:

root@turris:~# uptime
14:50:36 up 0 min, load average: 0.91, 0.24, 0.08

4

Can you try putting the USB flash into another USB port? And does it happen generally when you copy files or just with the large file you have on the flash drive?

5

hello it happens after a while reading file thus I think that its some buffer problem which resides in kernel. Can you reproduce it? BTW flash is fine - I can read files at my debian desktop. I will try change port later while I’ll reach router

6

Actually I had not problem with this flash before I have upgraded to 3.3

7

I’ve just tried it on two routers, one with the latest kernel in our test branch, one with the same you have. Running the cat command and copying a 1 GiB file from a Kingston DTSE9 G2 flash does not do anything nasty. How big is your file?

I moved flash drive from USB1 to USB2 but problem persists:

root@turris:~# uptime
10:27:08 up 1 min, load average: 0.55, 0.20, 0.07

11

and other observation:
Now I tried scp file from my laptop to SD card and router got frozen. After reboot file have 515899392 size

Sorry, but I can’t reproduce it on any of my routers - including one in the RC branch, which should have the same update history as your router. If there’s nobody else with this problem to pinpoint a common cause, I can recommend following:

  • Try connecting to the USB-serial console and trigger the bug, if something appears in the output
  • Force-reinstall kernel and all modules
  • Backup config and reset the router to factory defaults, ideally update it from SD card with latest image (the most brutal measure…)
13

I reinstalled the router a day before upgrade to 3.3 to get ubifs version. Is it really needed to reinstall again?

14

See USB3 is completely useless with latest update

musim reportovat, ze ani verze 3.5 neodstranila samovolny reboot pri cteni velkeho objemu dat z karty

Hello all if anybody have same problem it was caused by faulty memory chip. Thanks to CZ.NIC for a new RAM. Problem solved!
