Hmmm... interesting. Can someone please strace the polling process and see
what's going on? Attaching strace to the hal-addon-storage should do the
trick, Kay, right? It could be that TUR result is alternating. The problem
probably is that windows doesn't use TUR while polling for media presence while
we do. There are drives which completely check out after being polled for a
while and this bug report looks like another strain of the same problem. I'll
try to implement media presence polling inside kernel and use only
GET_EVENT_STATUS_NOTIFICATION as windows does. Please cc anyone with
reproducible problem cases here.
Thanks.
