Hi,
with openSuSE 11.1 I have the problem that the HD freezes for a certain time. /var/log/messages shows the following

With 10.3 and WinXP I never had this problem (because it’s a dual boot).

Does anyone has a idea what the problem is?

Thanx

I’ve found the same symptoms on one of my computers too. This system uses raid1 and it has happened two times now in the past 2 months. After the first time I did a RMA on the harddrive and they found no errors on it. I did however get a new drive and now it has frozen again.

One odd thing is when booting, the SATA link gets 3.0 Gbps but after a freeze it tries with 1.5 Gbps.

The SATA cable did seem to be so robust so maintenance people did not change it the last time despite my orders of a cable change :frowning:

Now the big question: Is this a driver problem or a cable problem. The system is used 24/7 so it’s difficult to test new kernels, change cables etc in trial and error strategy.

Relevant log messages below.

Hi,
wich file system you are using? I have reisefs installed, maybe this is the problem
