#11 System hang in ivtv_sleep_timeout
Using ivtv + 2.6.0 kernel patches, system locks while
modprobing ivtv. With mod option "ivtv_debug=127"
system stops after message "Sleeping for 600ms (600
recommended)". Looking in ivtv_driver.c it seems that
this is happening in ivtv_sleep_timeout.
This happened with CVS_LATEST downloaded on 1/10/2004,
and ivtv-0.1.7. Both with 2.6.0 kernel patches
obtained from ivtv wiki.
