http://bugzilla.novell.com/show_bug.cgi?id=630422 http://bugzilla.novell.com/show_bug.cgi?id=630422#c2 --- Comment #2 from Carlos Lange 2010-08-15 18:00:09 UTC --- I installed 11.1 back in a new partition and there was no error during installation and update and I was able to transfer 15 GB of data without incident or PCI bus error. So, I think 11.3 is reporting a hardware error incorrectly. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I reinstalled 11.3 from scratch in my laptop and kept my home unencrypted. When I try to copy with scp from the remote machine to my laptop, I get every time the MNI error after approximately 2.4GB transfer. This time the reason reported is "b0 on CPU0". But when I scp from the laptop to bring the data from the remote machine, then I am able to transfer without any problems. The largest folder I copied was 4GB. And it was the same folder over the same place where the remote copy starting from the remote had failed. Definitely not a hard disk problem. How can I give more diagnostic? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It also happened twice when starting the remote copy procedure from the local laptop. The last time I got a much longer error message, which mentions a CPU synchronization error and states "This is not a software problem!" Since the error message does not get saved to a file, I took a picture and I am sending it as attachment. The message says in part: Machine check: Processor context corrupt Kernel panic - not syncing: Fatal machine check on current CPU Pid: 0, comm: swapper Tainted: G M 2.6.34-12-desktop #1 I went back to the 11.1 installation and stress tested the machine copying my remote data several times over and I did not get any problems! (no errors related with the kernel in /var/log/messages.) The 11.1 installation uses kernel version 2.6.27.48-0.2. Is the new kernel seeing a real hardware problem that the old kernel does not see? Is there any boot flag I can set to make the new kernel more fault tolerant? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Kernel error happened after 5GB transferred with the "default" version. No kernel error happened after >45GB transfer with the "desktop" version of the 2.6.34-12 kernel. And both .34 versions support well my tablet, so I am sticking with the desktop version and declaring this a kernel bug. I am willing to help find the culprit in the default kernel, if you want me to. Or else, we can declare the issue solved. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
