Please respond. > > http://bugzilla.kernel.org/show_bug.cgi?id=7547 > http://bugzilla.kernel.org/show_bug.cgi?id=7805 The problem is that when you run pktsetup, the driver will open the cdrom device and keep it open. A very long time ago, the driver didn't do that, but that caused other problems, see for example: http://herbie.ucs.indiana.edu/hypermail/linux/kernel/0407.0/0761.html I don't know how to fix these problems in the kernel, but I know that an old idea from Jens Axboe was to merge pktsetup and mount in user space so that pktsetup only needs to run when you are actually going to use packet writing. -- Peter Osterlund - petero2@telia.com http://web.telia.com/~u89404340 ^ permalink raw reply [flat|nested] 2+ messages in thread

In bug 7547[1], somebody is issuing START_STOP to the ODD repeatedly which times out if the drive is empty. Is this coming from PKTCDVD or from userland polling? Also, do you mind adding yourself to the bug so that I don't have to relay? Thanks. -- tejun [1] http://bugzilla.kernel.org/show_bug.cgi?id=7547 ^ permalink raw reply [flat|nested] 2+ messages in thread
