Bug#966544: [Pkg-net-snmp-devel] Bug#966544: Bug#966544: snmpd: extend option broken after update
Hi, same here, woke up this morning to dozens of alert emails because extend support is suddenly "removed" without any change logs indicating this, nor in the man pages. The snmpd runs in read-only mode here as well. Alternatively, can you please provide a valid method of getting extended data into snmpd with the same ease as 'extend' feature offered? Kind regards, Rudi Daemen
Bug#864074: defaults.vim: broken configuration
Hi all, For all of those that are googling for this issue and want a quick work-around in place until the order-of-inclusion is fixed upstream, I have added the following two lines to the beginning of the system-wide vimrc.local on all debian servers I am managing: runtime! defaults.vim let g:skip_defaults_vim = 1 The first line, ofcourse, is only needed if you actually want some of the values from the "defaults.vim" file, otherwise it can be omitted. The second line avoids it from being loaded again at any later stage. I can confirm this works as it does load the defaults.vim (and thus some config options I do like) but it does this before processing the remainder in vimrc.local. As a result, it now no longer overrides any config options I did not like and thus changed in vimrc.local (e.g. set mouse=). Just adding these two lines to the vimrc.local file resolved my problems with vim. Kind regards, Rudi
Bug#517748: linux-image-2.6.26-1-686 System locks up under heavy disk load (MD Resync e.g.)
Here's an update. With an Ubuntu Live CD (using 2.6.24) I could mount the raid sets and recover just some data without issues. I rebuild the system using Ubuntu with a 2.6.24 kernel. All issues with the disk performance/corruption are gone now. The system is racing at full speed again with this kernel. For me this confirms there's something seriously wrong in the 2.6.26 kernel. I am guessing the problems I've had are all related (with the promise controller and with the new Sil3124 controller) because I've had nothing but trouble with disk access ever since I got to the 2.6.26 kernel. Fix or workaround? Install a 2.6.24 kernel rather then 2.6.26. Too bad that kernel version is no longer in the Debian repositories.

Bug#517748: linux-image-2.6.26-1-686 System locks up under heavy disk load (MD Resync e.g.)
If I had a test system on which I could try that, I would. Unfortunately, the affected machine is the production server. VMware (used for testing) is not affected by this bug.

Bug#517748: linux-image-2.6.26-1-686 System locks up under heavy disk load (MD Resync e.g.)
FYI: My system died on FS corruption. Did not notice this because mdadm did not report any errors. I noticed it because the system started to lock up. After a reboot, it did a fsck (which segfaulted) and the system hung afterwards. The system behaviour seems like this kernel bug describes: http://bugzilla.kernel.org/show_bug.cgi?id=11328 mdadm reports both arrays as healthy, but secretly all data was being corrupted. Maybe add a reference to this bug? I know this bug is directed at the HPT driver, however due to the similarities in the problems it could be a bigger, underlying, problem. I'm going to try and rebuild the system using a 2.6.24 kernel since that is the last kernel which did not report data corruption problems when using with mdadm.

Bug#517748: linux-image-2.6.26-1-686 System locks up under heavy disk load (MD Resync e.g.)
Hello, Here's an update. I replaced the Promise Controller with a Sil3124 based controller. The soft-lockups appear to have gone, however now the behaviour changed. I receive netdev watchdog alerts for my Via Rhine based NIC's and SATA bus resets on all four drives under heavy load (resync for example). See attached log for the events. I must add, these resets did not occur when using the Promise controller. The excessive NCQ failures noted in the log first made me think one of the disks was faulty, but all four disks at the same time? What are the odds... Smartctl does not report any problems with any of the four drives. Included the following output: - cat syslog | grep kernel - lspci -v - hdparm -i /dev/sda, sdb, sdc and sdd I just updated the BIOS rom for the mainboard, the SATA Bios is up to date (even disabled the onboard disk controller). This unfortunately did not make any difference. Might there be a problem with the Via CX700 chipset that could be causing this? The system is running the current stable release debian lenny kernel (linux-image-2.6.26-2-686, ver. 2.6.26-19) Best regards, Rudi Oct 3 11:34:01 palm kernel: [ 2140.080165] NETDEV WATCHDOG: eth0: transmit timed out Oct 3 11:34:01 palm kernel: [ 2140.080396] eth0: Transmit timed out, status , PHY status 786d, resetting...

Bug#517748: linux-image-2.6.26-1-686 System locks up under heavy disk load (MD Resync e.g.)
Giulio, I am not using the VIA boards IDE/SATA controller, only a PCI based HostRaid controller from promise. The onboard controller is actually a SATA and IDE controller: I just set it up to not use SATA due to boot problems with the Promise card if the onboard SATA support is enabled. As of today, none of the kernel updates to date have fixed the issue, I'm currently searching for a decent alternative for the promise controller (Non-RAID, 4 port PCI-SATA controller) and intend to replug the softraid arrays to that controller. I will post follow-ups once I have replaced it. Regards, Rudi -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Bug#517748: linux-image-2.6.26-1-686 System locks up under heavy disk load (MD Resync e.g.)
I have not been able to reproduce the problem on my testbox (Since I test this onder VMware, hardware is not comparable to the production machine). I did update the kernel with the newer version in te repositories (Now running linux-image-2.6.26-1-686, 2.6.26-13lenny2) but the problem still exists. To keep the system workable (and prevent long lockups) I set the resync speed to 2MB/s resulting in a two day resync time for the array. Though even at 2MB/s the system still lockes up only for shorter periods of time. Still getting the same messages in dmesg, see attached txt file.
