kmod-xfs-2.6.18-8.el5 missing from extras
by Farkas Levente 13 Oct '07

13 Oct '07

hi, the kmod-xfs-2.6.18-8.el5 rpm missing from extras. since this is the base kernel shipped with centos/redhat it'd be useful to include kernel modules for this kernel in extras too. since all installer (cdrom, network, etc) use this kernel for boot and install. therefore if someone like to create a new initrd (eg for new network card or filesystem support) than the easiest to modify the shipped inird. that's whay i need kmod-xfs-2.6.18-8.el5 too. thanks in advance. -- Levente "Si vis pacem para bellum!"

kernel module for RTL8110SC in centos-5 (r1000 vs r8169)
by Farkas Levente 08 Oct '07

08 Oct '07

hi, many intel motherboard use RTL8110SC network adapter. there is a description on page: http://wiki.centos.org/HardwareList/CentOS5/RealTek/r1000 how one can use r1000 kernel module for centos. unfortunately this driver seems to wrong. if you read carefully realtek download page and the latest source of r1000 (1.07) the r1000 is _only_ for 2.4.x kernel and for 2.6 it's called r8169! the worst thing r1000 seems to working most of the time but at random stage it stop working (eg: after init 4). the source you can download from realtek r8168... is more stable on 2.6.x kernel. i try to add this info to the above page, but it's immutable. in the mean time you can download kernel modules from here: http://www.lfarkas.org/linux/packages/centos/5/ -- Levente "Si vis pacem para bellum!"

Xen crash
by Nicolas Sahlqvist 08 Oct '07

08 Oct '07

Hi Centos-devel, I'm new to this list and joined since I am volunteering as a tech admin for a non profit organization called CouchSurfing (.com) where we tried to move the web servers to Xen zones and this has proven quite unstable since the our defined zones tends to crash on a daily basis with the latest CentOS 5 Xen updates. The physical boxes have 2 quad core 1.6GHz Xeon CPU's and 4 GB RAM, there is currently only 1 domain on each box, configured with 2.2GB RAM. Domain 0: [root@nd10254 ~]# rpm -qa | grep xen xen-libs-3.0.3-25.0.4.el5 kernel-xen-2.6.18-8.1.8.el5 kernel-xen-2.6.18-8.1.14.el5 xen-3.0.3-25.0.4.el5 Web1: [root@web1 ~]# rpm -qa | grep xen kernel-xen-2.6.18-8.1.8.el5 kernel-xen-2.6.18-8.1.14.el5 The Domain0 zone is indeed rock stable, while the Web1 etc. are crashing daily with the 2.6.18-8.1.14 Xen kernel and the stack trace we see after a few hours is as follows: BUG: soft lockup detected on CPU#5! Call Trace: <IRQ> [<ffffffff802a76ad>] softlockup_tick+0xdb/0xed [<ffffffff8026ba66>] timer_interrupt+0x396/0x3f2 [<ffffffff80210a87>] handle_IRQ_event+0x2d/0x60 [<ffffffff802a79ec>] __do_IRQ+0xa4/0x105 [<ffffffff802699b3>] do_IRQ+0xe7/0xf5 [<ffffffff8038dde8>] evtchn_do_upcall+0x86/0xe0 [<ffffffff8025cc1a>] do_hypervisor_callback+0x1e/0x2c <EOI> [<ffffffff802063aa>] hypercall_page+0x3aa/0x1000 [<ffffffff802063aa>] hypercall_page+0x3aa/0x1000 [<ffffffff8026afe2>] raw_safe_halt+0x84/0xa8 [<ffffffff802684f8>] xen_idle+0x38/0x4a [<ffffffff80247bcd>] cpu_idle+0x97/0xba BUG: soft lockup detected on CPU#7! Etc., etc etc, It does not crash the Xen zones directly, but clogs up the Xen web1 console etc. We did not see this when running the 2.6.18-8.1.8 Xen kernel, instead the Xen zones crashed less frequent with a out of memory problem as follows: Call Trace: [<ffffffff802aeefc>] out_of_memory+0x4e/0x1d3 [<ffffffff8020efe8>] __alloc_pages+0x229/0x2b2 [<ffffffff8023fd5b>] __lock_page+0x5e/0x64 [<ffffffff80232637>] read_swap_cache_async+0x42/0xd1 [<ffffffff802b32a2>] swapin_readahead+0x4e/0x77 [<ffffffff8020929d>] __handle_mm_fault+0xae3/0xf46 [<ffffffff80260709>] _spin_lock_irqsave+0x9/0x14 [<ffffffff80262fe8>] do_page_fault+0xe48/0x11dc [<ffffffff80207138>] kmem_cache_free+0x77/0xca [<ffffffff8025cb6f>] error_exit+0x0/0x6e We think the whole problem is how the kernel fails to handle resource cloging (to many interrupts, heavy CPU and memory usage in the defined zones etc.) from stubmbling on some fuzzy posts on the net, example: http://article.gmane.org/gmane.comp.emulators.xen.user/26617 Is this problem known to you or new, any ideas on howto resolve it? Regards, Nicolas Sahlqvist CouchSurfing,.com

fedora-usermgmt equivalent
by Kenneth Porter 08 Oct '07

08 Oct '07

I'm looking into migrating the openpbx package from Rawhide to Centos, and it has a BuildRequirement on fedora-usermgmt-devel. Is there an equivalent package in CentOS, or how does one structure the spec file to allow building for either distro?
