** Description changed: - I reported this bug thinking that it was an issue with /tmp, as you can - see below. But since then, I have tested much more, and the issue - "feels" like DMA is turned off. + This happens when you have both your burner and your HDD connected to the same IDE cable. It can also happen in some notebooks. Here is the fix: + In K3b: + Settings > Configure K3b... > Programs > User Parameters + Click near cdrecord, and add the option -immed. - I recently tested burning on Windows, and I realized that I had - forgotten how fast a computer I have. On windows, I can burn the cd - without any slow downs; I can even defrag my harddrive without a hiccup. - - The cd that I burn is a rw, and it burns quote slow, only 4x. But, on - linux, that is enough to drag to a stand still, and the system monitor - reports the cpu burning away in io wait. - - I have tested with brasero of course, but also allot with k3b, on - several clean installs including a 64bit. - - I have a P5B motherboard: http://asus.com/product.aspx?P_ID=YwIVDOTcvIMHZdTy - My cd rom and HDD are both hooked into the IDE cable, which I believe is the jmicron controller. (the mobo is geared toward SATA, but I built this as an upgrade from a computer geared towards PATA, and just used the HDD and CD from that) - - - --old-- - Brasero uses /tmp for its temporary work space. /tmp is just a directory on the harddrive, its not RAM. Thus, when brasero tries to do a bunch of work, it ends up swapping to the harddrive, even though you have plenty of ram. - - The work around is to go into properties, and use any tmpfs mount point, - which uses the RAM, like /dev/shm - - I guess /tmp is for temporary files that you aren't doing allot of I/O - on. Anyway, I don't really know whats going on. I don't know why - brasero is using files in the first place. I switched, and saw no - noticeable increase in my ram usage, so its not like brasero needs a - large working space. I don't understand why brasero isn't just - allocating the memory it needs, like every other program does. + You may need to ensure that cdrecord is selected by: + Settings > Configure K3b... > Advanced > Show advanced GUI elements + During the burning setup, you will have an option to select cdrecord.
