hi, I am Manoj from Mumbai, India. I am having problems with my USB 2.0 pen drive on linux. i am having the same problem on almost all linux distros i tried and i think it might have something to do with the linux usb drivers. i am not sure though, please correct me if i am wrong. i don't mind a detailed explanation as to why this is happening :).
I have a 2 GB USB pen drive. while writing large amount of data (~2GB) to the pen drive , the kernel load( as shown by gnome system monitor applet) shoots up to around 6 to 7, the entire gui becomes very unresponsive and the system feels laggy. i have 1 GB Ram. the mem usage during the transfer is quite high and eats almost my entire Ram. my home machine is a gentoo on amd64. i tried it on ubuntu, mandriva and fedora i386. all had the same issues. Also, sometimes, it takes a lot of time (about 2-3 minutes sometimes) to unmount the pen drive. apparently, some amount of the data to be transferred is cached and it is flushed to the device only when i give the umount command. i am using default I/O scheduler - "CFQ" and pre-emption model - "voluntary kernel preemption(Desktop)". thanks. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
