Package: hal Version: 0.5.10-4 Severity: normalAccording to powertop, hal polls the CD drive very often[0], which causes about 35 wakeups per second. Polling the drive no more than once a second or using an asynchronous notification method (if such a method exists) would be much preferable.
Disabling the polling of the CD drive disables these wakeups, but I'd prefer not to have to do that.
Note that I am using a PATA cdrom with libata.[0] I suspect it is 10 times a second, because that's the number of libata wakeups I see, but I haven't actually checked.
