Strange content in the kernel dmesg traces
by Mark Hull-Richter 28 Apr '07

28 Apr '07

I am experimenting with the kernel (as some of you may know), and I have added a whole slew of traces in some relatively sensitive code in the lower levels of the page cache and i/o functions. Most of this tracing not only works but is highly revealing as to what the kernel is doing and why. However, I am now getting this odd content in the trace log (dmesg), and I cannot figure out what it is or why it is there. If anyone recognizes this situation, I invite comment and suggestions on how to eliminate or decipher it: 4296757675 pdflush(80): do_writepages: map>ops>wrtpgs ffffffffa0195ff5 4296757675 pdflush(80): mpage_writepages w/b index 49728 pages 256000 <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7>__bio_add_page: 2x ph 88>128 || hw 88>88 || 360448>max ffffffff802525d8 generic_make_request(bio 000001017c745300) 50729472, 704 __make_request(q 00000101b9293870, bio 000001017c745300: sdc; 50729600, 704) ll_new_hw_segment: 70 + 29 > 88 <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7><7> <7><7><7><7>__bio_add_page: 2x ph 88>128 || hw 88>88 || 360448>max ffffffff802525d8 generic_make_request(bio 000001017c745a80) 50730176, 704 __make_request(q 00000101b9293870, bio 000001017c745a80: sdc; 50730304, 704) 4296757684 swapper(0): dl_mv2dsp: sdc start 50710368 secs 1408 (The lines with the <7>s in them are long - I wrapped them for ease of reading and to keep the width down somewhat.)

recording sound: how 2 control recording level?
by fredex 28 Apr '07

28 Apr '07

Hi gang! I'm trying to record (to .wav files) sound coming in on the line input of my sound card (in this case, output of a tape deck). For LISTENING purposes, I can control the level with the Gnome Mixer. However, the RECORDING level is not affected by the mixer. As a result, the recorded audio is badly clipped and horribly distorted. I don't understand enough about how this stuff works to have a clue how to troubleshoot this problem. Can someone offer helpful advice? Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven." ------------------------------ Matthew 7:21 (niv) -----------------------------

Isa Soundcard under CentOS 5
by Olaf Mueller 28 Apr '07

28 Apr '07

Hello, Under Fedora Core 6 I used to integrate the soundcard of my notebook with modprobe snd-opl3sa2. Now, after changing my system to CentOS 5, I could not find this module for my isa soundcard any more. # ls -al /lib/modules/2.6.18-8.1.1.el5/kernel/sound/isa/ insgesamt 24 drwxr-xr-x 3 root root 4096 27. Apr 04:09 . drwxr-xr-x 9 root root 4096 26. Apr 18:15 .. drwxr-xr-x 2 root root 4096 27. Apr 03:36 sb Both system-config-soundcard and alsaconf, compiled from sources, don't find my isa soundcard. How could I get my soundcard working under CentOS 5? Thank you. regards Olaf

Problems with RAID0 array on new server
by Michael Slater 28 Apr '07

28 Apr '07

Hello, i recently installed Centos 5 on a new server with a single scsii disk. After the installation, i added 2 additional disks that were once the components of a raid0 array on another server. I get some errors and am unable to start the array the following is an extract from dmesg output: md: Autodetecting RAID arrays. md: could not open unknown-block(8,17). md: could not open unknown-block(8,33). i then examined each disk in fdisk Device Boot Start End Blocks Id System /dev/sdb1 1 17501 17921008 fd Linux raid autodetect Device Boot Start End Blocks Id System /dev/sdc1 1 17501 17921008 fd Linux raid autodetect I tried to re-create the array and get this: mdadm --create --verbose /dev/md0 --level=0 --raid-devices=2 /dev/sdb1 /dev/sdc1 mdadm: chunk size defaults to 64K mdadm: Cannot open /dev/sdb1: No such device or address mdadm: Cannot open /dev/sdc1: No such device or address mdadm: create aborted yet obviously the devices are there. what else should i look at. putting the drives back in the old server, and the array comes up with all data intact. Any ideas ? thanks, Michael ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

CentOS, RTL8196 and jumbo frames.
by Steven Haigh 28 Apr '07

28 Apr '07

Hi all, I've just upgraded my home network to a Linksys SRW2024 (with lovely vlan trunking support!) and I'm trying to enable jumbo frames. When I try to set the MTU of an rtl8169 based network card (it's a Netgear RA311), it comes up with an error stating: # ifconfig eth1 mtu 9000 SIOCSIFMTU: Invalid argument The only options it will take are 1500 or below. Does anyone know anything about this? Do I need to set something special? -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9017 0597 - 0404 087 474
