apport information ** Description changed:
I know that this BUG is killing MANY people for a looooong period of time. But still, the bug report for 197762 was kind of closed: no more comments and the advice that this is a hardware-dependent issue! Well, I disagree! There are many people using Ubuntu that have that problem - but nobody seems to care!! The symptom: when copying a file with several hundred MB in size (or larger) - the copy process starts fast (in my case >30MB/s) - but then, it dramatically slows down and gets slower and slower and slower!! The system load rises to levels > 6 (and NOTHING else is happening on the system at all!!). The copy process will finally come to a (successful) end - but it takes a long time: 2 GB copied in more than one hour!! Now: it might be "hardware-dependent" but definitely NOT a hardware failure! The same system under Windows: no problems at all! What I got: a Dell Latitude D830 with a Core2 Duo, 4GB of RAM - running the 64bit version of Ubuntu. This bug has been there for many Ubuntu versions: the first I started with was 8.04 - same issue!!! WOULD SOMEONE PLEASE TRY TO HELP??? Thanks!!! --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
