Hello grsecurity team,

when booting an server with 2.6.32.41 Kernel patched with grsecurity-2.2.2-2.6.32.41-201106132135.patch the hard interrupts ( hi ) from the CPU(s) are very high.

As an example:
Cpu0 : 31.4%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 68.6%hi, 0.0%si, 0.0%st
Cpu1 : 5.9%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 94.1%hi, 0.0%si, 0.0%st
Cpu2 : 10.8%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 89.2%hi, 0.0%si, 0.0%st
Cpu3 : 5.9%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 94.1%hi, 0.0%si, 0.0%st

[~/root]# cat /proc/loadavg
2.52 1.93 0.88 1/256 5898
[~/root]#

I have also tried to disable all GRSEC options fully in the kernel config, but the problem still exists.
The problem does not occur when booting the unpatched vanilla kernel with same config.

Thanks for your help.

Greetings,
Daniel

is the load actually this high or is it a problem with statistics only (maybe you can use perf to see what the CPUs are doing)? i'm asking it because we have another similar report: http://forums.grsecurity.net/viewtopic.php?f=3&t=2646 that may be related. also can you post your .config and what was the last version that you tried and didn't have the problem?

I face the same problem on gentoo x86 with 2.6.39-hardened-r2 kernel. Top shows 40-50% of hardware interrupts. If you need any feedback please ask for it.

I hope this helps you.
If you need more or other information, please feel free to ask for it.
Btw. the problem is reproducable on more than 20 servers.

Hi perlish,

perf ist part of the kernel source and can be found in the linux-xxxx/tools folder.

anyone managed finding a workaround ?

I believe the PaX Team has identified the issue (it was only an accounting reporting issue, not real load) and may have something to report soon.
