| |
Hi... this is my first bug report. I hope that it will help you.
Thank You
1. "DMA over CPU" memory leak if I burn Audio-CDs
2. I installed Linux 2.6.8.1 and tried to burn an Audio-CD. Then the PC swapped a lot until he freezes. I tried to increase the swap-partition without a success. Then I stopped burning with xcdroast and burned on the bash directly with cdrecord (dev=ATAPI:0,1,0). Then I saw always at the same time. DMA over CPU-Error... an many memory dumps rushed over my screen and he started "swapping to death" He killed some processes to get more memory (I have 256MB RAM and 384 MB swap). I am not able to print these Error-Messages, because I have no access to my PC then. Then I installed Linux 2.6.7 again and everything works probably.
3. hdd, memory, swap, dma over cpu
