slow writing on flash disk

[Codepoet]

I don't think it is something with KDE because it has nothing to do with the drivers. It's SUSE, maybe you got a newer kernel which does not support your device as good as the old on.

You can simply try if it is KDE or not: Go into runlevel 3 (console only) and try to copy some files on the shell.

maybe you'r right.
thanks, I'll try it next time I come home.

if it's true, any idea how to solve it? Must i downgrade my kernel? is there anything else i can do beside it?

[Codepoet]

Check whether your kernel was upgraded or not.

Another kernel would then probably help.
Try these: Your last kernel (should fix it), newest SUSE, newest standard kernel from kernel.org
Maybe even the mm series.

You could try a Knoppix or another live cd if it is slow...

thanks,

I've downgraded my kernel to the previous one since I cannot update it just because i access the internet from internet cafe which have tooo slow connection.

well, no change. I know my previous kernel did its jobs well. It seems that the problem is not with kernel. I still cannot figure out what the problem is. I've also tracked all updated packages, but no one is involving with i/o mechanism. So, i just leaved them alone.

is there any suggestion?

Btw, how about my second question (about kate)?

thanks again.

Hi,

Just wanted to say I noticed the same behaviour on my system, also SUSE10.
ir210, if you solve the problem, please post it here, I ofcourse will do the same.

[Codepoet]

If it's not the kernel I have no good idea... Did you try a live cd?

Kate and app crashes: Should not happen. With Gentoo I would say recompile but here... No idea

Hi,
just wanted to say I got a lead.
It looks like there are changes in the kernel about the FATFS, somthing to do with accessing the FS with a sync , which makes it slow.
See here:
http://www.ussg.iu.edu/hypermail/lin...07.3/1451.html
But its too late for me to read any more or try what they suggested there (changing the sync option in fstab).
But if someone can try it, or confirm it, before I get to try it tomorrw (err.. today) then please post!

Cheers.

any success, high_flyer? I still can't make it normal.

Didn't have time to test it yet (can you believe it??)
I am sooo busy its really crazy... got at 24:00 home last night, from work!!
I'll post as soon as I test it.
Did you try to take the the sync out of the mount command?
Dont forget to run sync before you take the USB stick out!

[ir210]

it's autodetected by hal. I donot know how to change hal configuration. I've tried to remount it with async option, but it still slow.

I have the same problem from console and gnome (you are, codepoet, right it's not kde's fault). It only happen to my suse not kubuntu 5.10 (which hasn't been updated yet).

[wysota]

could you show us the mount parameters frm that device?

[high_flyer]

Yes it works.
My original mount is:
mount -t subfs -o fs=floppyfss,sync,procuid,nosuid,nodev,exec,utf8=t rue
And the modified one:
mount -t subfs -o fs=floppyfss,procuid,nosuid,nodev,exec,utf8=true

Simply take 'sync' out of the line.
It works fast as it should this way.
Don't forget to run sync before you take out the memory stick, to make sure any buffered data is flushed.
