 Posted: Wed Nov 17, 2004 11:46 pm Post subject: Advice for Kernel Upgrade? |
 |
|
As it stands, I'm running dev-sources-2.6.4 on my Tyan Thunder K8W and I'm mostly happy with it, but there are a few issues, seemingly unresolvable:- nvidia drivers don't like it: It just flat-out refuses to detect the 2.6.4 kernel.
- latency: Performance is generally blazing fast, but every once in awhile there is ths odd... 'tic' is the only way I can describe it, where the system pauses a moment then resumes doing things at it's normal merry speed. This is especially evident in flash.
- radeon: Every once in a blue moon the radeon driver decides to stop working, and X falls back to software on everything. Usually I can rmmod -f and re-probe it to fix it, but sometimes trying that gets it stuck waiting in driver mode.
- rngd: When I tried to run seti multithreaded, un-niced CPU usage increased a /lot/. Checking top showed that the cuprit was actually rngd, which was happily consuming CPU time for no apparent reason.
- growisofs: This one I know is a kernel issue, if I burn a multisession DVD-R > 2GB mount fails on it, sometimes locking the entire system.
- missing symbols in firewire module: Luckily I don't need firewire, but it'd be nice to have there if I wanted it.
Since I haven't found any obvious solution for any of these(feel free to prove me wrong  ), I'm guessing these are kernel issues.
I suppose my kernel is getting a bit old by now, but my last upgrade attempt was not a happy experience -- no less than three of my modules had been renamed, lm-sensors stopped giving sane values, and trying to emerge nvidia-kernel caused a filesystem oops!  Luckily no permanent damage, yay for reiserfs, but I ditched that kernel and didn't look back.
Any advice on what kernel I should upgrade to next, before I brave the waters again?

Well...
I can't vouch for any of the issues you have, but I normally test a lot of kernels and I'm currently running mm-sources for all my needs. 2.6.10-rc2-mm1 is the current i use and it works like a charm and handles all my hw fine on AMD64.
I still have a bunch of older kernels laying around in my /boot partition and I always leave working kernels in my grub.conf so in case a new kernel failes, I can just reboot and select and older working kernel in order to boot the machine.
Try a newer kernel and see if it works on your HW, but don't get rid of your current working one.

Em, to the newest kernel perhaps? What exactly is your problem?
Maybe, you want to wait until this issues with root and cd-burning are solved (~2.6.10-2.6.11).
Or you want to wait for reiser4 support (~2.6.15-20).
A really good branch is the 2.6.7 series. |

I got told quite sternly that I couldn't expect to get any help at all if I used mm-sources, so unless that's changed that's not an option, sadly.  | Quote: | | I still have a bunch of older kernels laying around in my /boot partition and I always leave working kernels in my grub.conf so in case a new kernel failes, I can just reboot and select and older working kernel in order to boot the machine. |
Oh absolutely. I've got several versions of 2.6.4 alone under /boot, I never replace. | Lore wrote: | | Em, to the newest kernel perhaps? What exactly is your problem? |
My problem is, last time I tried upgrading my kernel(I think I tried 2.6.8 or 2.6.9) lots of stuff just plain Didn't Work(tm), they'd renamed 3 of my modules on me, and it nearly killed my filesystem. Not an experience I wish to repeat. | Quote: | Maybe, you want to wait until this issues with root and cd-burning are solved (~2.6.10-2.6.11).

But the longer I wait, the more modules they're going to rename on me. That's a real pain.

Help from whom?
Here?
I have never had any problems getting help with issues even though I have been using mm-sources as my main kernel both on x86 and amd64.

The IRC chan. I admit the forum is far friendlier.

Hmmm... Oh well, I never use IRC anyway.
Please feel free to post any problems with any kernel your try here and I will try to help if I can and I'm sure a lot of others using various kernel falvours will too.
