HI Marcy,
When you say SuSE's web site did you mean suse.org. I tried Novell's site but under the link below I couldn't find any of the kernel patches. Do you have a better link? Also when I tried rug I received the following: ERROR: 'kernel-default' is not available. http://download.novell.com/index.jsp?product_id=&search=Search&families=2658&version=19925&date_range=&date_start=03+Jun+2009&date_end=03+Jun+2009&keywords=kernel&sort_by=&results_per_page=&x=36&y=7 (Embedded image moved to file: pic30932.jpg) Thank you David Kelly The Supreme Court of Virginia Marcy Cortes <marcy.d.cor...@w ellsfargo.com> To Sent by: Linux on LINUX-390@VM.MARIST.EDU 390 Port cc <linux-...@vm.mar IST.EDU> Subject Re: High interrupt rate 05/29/2009 03:21 PM Please respond to Linux on 390 Port <linux-...@vm.mar IST.EDU> You can either grab the rpm off of SuSE's website or run "rug install kernel-default" .

The kernel that comes with sp2 was 2.6.16.60-0.21, and the most recent kernel for sp2 is 2.6.16.60-0.37 (remember that the number after the "-" is the rpm build/release version, so that will be different between distros). I am not sure want the underlying problem was, but from this mailing list it seems there was a bug in the sles10sp2 kernel and it's fixed with the newest. So unless someone else would like to explain the bug, that's all the information I have. The cause is that the application asks for a wakeup in 1 ms or so (this is silly design since it is polling). The kernel only provides 10 ms granularity and rounded incorrectly to 0 ms, thus making the silly thing pretty bad. It also shows very high CP overhead when this happens. The fix is that the kernel rounds it to 10 ms to limit the impact. Martin just told me the fix is in: 2.6.18-124.el5 für RedHat RHEL5 und 2.6.16.60-0.34 für SuSE SLES10 -- Rob van der Heij Velocity Software http://www.velocitysoftware.com/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
