Maintainer's patch recreated with gendiff
I have backported the maintainer's patch to the latest RHEL4 kernel and posted it to rhkernel-list yesterday. I got an ACK in rhkernel-list today. Here is an additional information. I got another Ack in rhkernel-list the other day, so now there are 2 Acks from engineers. By the way, here is an information about the patch and the testing that I have done. I have mentioned about them in rhkernel-list, but it seems that I haven't mentioned much about them here. A fix patch for this problem, which the maintainer has created, has already been in the mainstream. I have backported it to the latest kernel of RHEL4 and done test on a ia64 machine that has hotplug PCI slots. Here is the results of the test. [root@primeq1 ~]# cat /sys/bus/pci/slots/19/power 1 [root@primeq1 ~]# echo 1 > /sys/bus/pci/slots/19/power [root@primeq1 ~]# cat /sys/bus/pci/slots/19/power 1 [root@primeq1 ~]# cat /var/log/messages | tail -2 Sep 30 10:52:18 primeq1 ntpd[4949]: kernel time sync disabled 0041 Sep 30 10:52:49 primeq1 kernel: shpchp: shpchp_enable_slot: already enabled on slot(13) An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below.
