Hello all,
I recently installed SUSE 11 and every time I copy from or to an USB device at some random point during the copy the system hangs. No reactions from keyboard, screen or network.
I used to have SUSE 10.3 and I never had this problem. I did a new install but I kept home on a different partition so I kept all data and settings.
It’s kinda hard to update my iPod now 
Does the dmesg output show anything?
I don’t have an iPod, but I can copy to/from my USB stick just fine with 11.0.

Is dmesg the /var/log/messages log?
I need to check it after the system boots again.

No - /var/log/messages does not start immediately. Most of the device detection
log information never gets there, but is kept in a volatile buffer in the
kernel. The dmesg command dumps that buffer.

How can I check dmesg when the system hangs then?

The output of ‘dmesg’ is dumped/saved in ‘/var/log/boot.msg’. The PREVIOUS
boot’s dmesg is in ‘/var/log/boot.omsg’.
Each boot, /var/log/boot.msg is moved to /var/log/boot.omsg, and a new
boot.msg is created.

Obviously you cannot. If you have any time window between initiation of the copy
and the hang, start the copy and then press CTRL ALT and f10. This will let you
see the log messages. Perhaps that will show what is happening.
Do you have another computer on your network? If so, what OS is it running?

I’ll turn on the iPod sync late at night then with the dmesg screen on. It will take hours to sync anyway.
I have 5 machines connected to my network,
3 openSUSE 11
1 OES 2
1 Wii 
I also copied large files from my laptop (SUSE 11) to my iPod without problems, so far.

As you have other machines, it may be possible to capture any dump information
using netconsole. See Documentation/networking/netconsole.txt in a source tree,
or http://www.mjmwired.net/kernel/Documentation/networking/netconsole.txt to see
how to set it up.

Unfortunately, the information about a crash is not preserved in /var/log/boot.msg.

{Smile} I know that. But that wasn’t the question.
Information about the crash would be in /var/log/messages, if anywhere.

Last night I got kernel 2.6.25.11-0.1-pae and after the reboot I synced my iPod, over 30GB, without problems… That was the first time since openSUSE 11 I could copy that amount of data to or from an USB device.
I’ll try it again this weekend as test, also from another device.
