* Some problems with HP DL380 G8 BIOS and SLES11 SP3 @ 2014-08-13 15:22 Ulrich Windl 2014-08-14 17:46 ` Don Zickus 0 siblings, 1 reply; 6+ messages in thread From: Ulrich Windl @ 2014-08-13 15:22 UTC (permalink / raw) To: linux-kernel Hello!

In order to accomplish they need to use a perf counter or two, hence the conflict. Set the firmware setting to OS control and the problem goes away. Contact HP for those instructions, they are very aware of this problem and recommend OS control to all high end servers.

Thanks for answering, but the BIOS has set power management to "OS control" (see attachment). So I guess it must be something different.

So I guess it must be something different. Hmm, sounds like it. Regardless, the error message indicates the counters are in use most likely by the BIOS. So you can ask HP what is going on. I assume this is a normal bootup and not a kdump crash kernel, correct?

I'm afraid the standard hardware support at HP does not care much about such issues (I remember those Xeon bugs that caused memory errors during longer idle phases (in the G7 server) that are fixed be recent microcode updates: HP changed memory modules, and they changed the board, but it took very long until they updated the BIOS). Is there any more information I can provide to narrow down the problem?

I'm afraid the standard hardware support at HP does not care much about such issues (I remember those Xeon bugs that caused memory errors during longer idle phases (in the G7 server) that are fixed be recent microcode updates: HP changed memory modules, and they changed the board, but it took very long until they updated the BIOS). > > Is there any more information I can provide to narrow down the problem?

And sure enough the fixed counters (38d) have counter 1 and 2 enabled (330) before the kernel even touches them. The assumption is if someone is using them, then anything the kernel does with them could be inaccurate. My contacts with HP here tell me that if the power control is setting to OS, then the counters should be unused and not be set (and we have seen that here at Red Hat). There isn't much more I can say and I am not really motivated to walk through all your BIOS options to verify everything. :-) At least with RHEL kernels, there is supposed to be published HP whitepapers detailing all this and what to do.
