#42 Computer reboots when I try to view video

[maslovalex]

Hi.

I'm using Fedora 5 spca5xx-20060501.
kernel 2.6.16-1.2122_FC5
gcc (GCC) 4.1.1 20060525 (Red Hat 4.1.1-1)
WebCamera: Creative WebCam Instant (lsusb: ID 041e:4034
Creative Technology, Ltd)

Compilation and installation goes fine.
After I plug camera, there are following messages in
/var/log/message:

Looks fine. But when I'm tring to use camera (watch
image) system reboots. CamStream sees camera, Ekiga
sees camera, HardwareBrowser also.

These are lines from message.log just before system
reboots when I try to run spcaview :

If it is possible to get more information to be able to
fix such a behavior, just let me know and I'll try.

thx in advance,

At line 33 you have :
CFLAGS += $(DEFINES)
Replace it by :
CFLAGS += $(DEFINES) -fno-unit-at-a-time

At line 107 you have :
CFLAGS = -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe
Replace it by :
