Hello,

Can you please reproduce with a non-tainted kernel? I.e. don't load the nvidia module.

Best regards
Uwe

Hi Uwe,

I will try.

During a week (Sep 27 to Oct 5) has been working well.

With the kernel 2.6.29.5-rt22 did not have any errors.

Hello Jose,

hmm, i have a similar issue with my network interfaces on one special computer. At first I thought it is a bug in some pci card driver. But since the same setup works on a mainboard with different chipset and CPU, I do not assume that any longer.

My computer with the similar issue has an nVidia chipset, see lspci beneath. Does your computer have the same chipset?

If so, do you have problems with a non-rt kernel, too?

Best regards
Uwe

In my case, only with rt kernel.

Hello Uwe,

no, without preempt-rt patch it runs fine.
