Having kmemleak turned on at least in rawhide is a good thing. As for a released kernel, I'd agree that the kthread Catalin uses probably affects battery life. Of course you could disable it, but I suppose you mentioned this because of the default - hence, copying fedora-kernel so that someone can actually answer your question. Jon.

When it comes to dealing with online merchants, what the sales contact at the manufacturer says will not be sufficient reason for return for a full refund, of a device which turns out to be unsupported. My question to you is - why do you have to resort to assuming such a pompous attitude via questions like "Your thought process intrigues me." There is a fitting description for such attitude, but I will not spam this mailing list with such a vivid description. > Some basic investigation > on the web will tell you what you need to know: > > http://wiki.debian.org/ath9k#supported > > Generally I just plug shit in and it works. > > Christopher Brown _________________________________________________________________ Get your vacation photos on your phone! http://windowsliveformobile.com/en-us/photos/default.aspx?&OCID=0809TL-HM

Dear List, I searched the ath9k source directory /usr/src/redhat/BUILD/kernel-2.6.29/linux-2.6.29.i586/drivers/net/wireless/ath9k for any strings that would hint/suggest support for the Atheros 9220/9223 chipset. I saw no such strings. So, I emailed Atheros.com sales dept. and asked if they intend to provide an open source driver for the AR9000 series chipsets, esp. the AR9220/AR9223. They replied that they already DO support the AR92xx chipset in the ath9k driver. Before I go out and purchase the mini-pci card, is it true that the ath9k driver has ineed been tested to fully support AR9220/AR9223 chipsets?? Thank you, Markus _________________________________________________________________ Express your personality in color!

kernel 2.6.29.6-217.2.3.fc11 compiled from source will not boot‏‏
by Markus Kesaromous 10 Aug '09

10 Aug '09

Dear list, There is something seriously wrong with this kernel release. It compiles - but will not boot all the way. It hangs somewhere. I even tried to boot into single user mode. I never get to the shell prompt when booting in single user mode, nor to the gnome login banner when letting it boot in multiuser mode. After some 30-45 minutes I Ctrl-Alt_Del and the kernel pops the message Stopping all md devices .. and the pc reboots. I did not have this problem with these kernels 2.6.29.6-213.fc11 2.6.29.5-191.fc11 Are there others who have tried to build 2.6.29.6-217.2.3.fc11 from source rpm and configured the kernel in any way before building? Did you see any errors when running make modules_install as I did? Did the resulting kernel boot up all the way? If you need more info, please let me know. Cheers, Markus K. _________________________________________________________________ Windows Live™: Keep your life in sync. http://windowslive.com/explore?ocid=PID23384::T:WLMTAGL:ON:WL:en-US:NF_BR_s…

enable CONFIG_IMA
by Eric Paris 03 Aug '09

03 Aug '09

Just noticed that the F12 kernel have CONFIG_IMA turned off: # CONFIG_IMA is not set I'd like to see: CONFIG_IMA=y CONFIG_IMA_MEASURE_PCR_IDX=10 CONFIG_IMA_AUDIT=y CONFIG_IMA_LSM_RULES=y This should ONLY be enabled for 2.6.31 kernels as before my patches in 2.6.31 there were a couple of normal user trigger-able security issues with IMA. Without configuration on the boot line or configuration after boot of the ima infrastructure there is no impact to building this piece of code outside of the fact that it builds CONFIG_TCG_TPM and CONFIG_TCG_TIS in and will not allow them to be built as modules. This may cause some consternation on users of the latest lenovo thinkpads who have to patch those modules to get them to work (TPM on latest lenovo notebooks only supports ACPI not PNP for device discovery), but seeing as how noone really uses the tpm anyway and hopefully it'll be fixed upstream this week I don't see that as a large problem.... -Eric
