Package: spca5xx-source Version: 20060202-1 Hi, when running spca5xx module on a PII IBM Netstation system with a Kernel 2.6.16-rc6 i am seeing this oops on the first invocation of vgrabbj to capture a single image (vgrabbj -d /dev/video0 -f f.jpg)
The kernel line says:
263 if (tasklet_trylock(t)) {
264 if (!atomic_read(&t->count)) {
265 if
(!test_and_clear_bit(TASKLET_STATE_SCHED, &t->state))
266 BUG();
267 t->func(t->data);
268 tasklet_unlock(t);
269 continue;
270 }
271 tasklet_unlock(t);
272 }
