weird temporary GUI freeze/lag/stuttering wireless related
hi... i'm having a minor issue with my new laptop... it's a Dell Inspiron 640m/e1405... it has Intel 3945 wireless... i'm running Ubuntu 6.10 (Edgy Eft) on it... i'm using whatever ipw3945 and wpa supplicant came with the distro and my connection type is WPA2 Personal... my router is a WRT54G v3.1...
when i'm on the wireless connection i sometimes get disconnected and stuff, which is normal cuz of interference, range etc... but the problem is that sometimes while i'm getting disconnected, the GUI will start to "stutter"... i'm not exactly sure how to describe it... think of little split-second freezes, a few in a row... during these split second freezes, the mouse pointer won't move and anything else like windows or even the keyboard will stop moving/working... once the connection is back, everything is back to normal... the problem seems to start when the connection fails, and it continues happening while re-establishing the connection...
i'm using network-manager-gnome, so i can actually see when the problem is about to happen cuz i start losing bars in the applet... then i lose all the bars and the (physical) wireless LED on the front starts to blink really fast and stuff...
anyhow, i'm trying to figure-out where the root of the problem lies... i suspect it's a bug in the crappy intel closed-source driver or firmware, but i'm not sure... i was wondering if anyone else has experienced something similar, or if you could help me further diagnose and and try to find a solution for this... i'm new to the whole laptop and wireless thing so any help is GREATLY appreciated...

I've experienced this on a previous Linux setup under RedHat 9. The moment I started copying anything from another PC over the LAN, I'd get "microfreezes" / gui stuttering just like you describe with your wireless connection dropping. In my case I eventually traced the problem to not having DMA support in the kernel under RedHat 9 for my particular motherboard. This meant that all IO on the board was done non-DMA, i. e. the CPU had to drop whatever it was doing every few microseconds and go do IO scutwork, instead of having the DMA controller handle the transfers. Thus, the moment I started to "push" my system with bulk-IO, it would start stuttering.
The first thing you might check is that the kernel you are using has support for your motherboard chipset compiled in... chances are it doesn't, so the kernel if not using DMA on your board. The reason I think you see stutter when your wireless is connecting / disconnecting is that this requires a lot of data to be shifted around (DNS / authentication / negotiation...?) and because you (maybe) do not have DMA active, the CPU gets so involved with shifting data around that your userland processes get shafted as regards processing time as the CPU is busy doing transfers manually to get your connection up...?

hey there... thanks for the reply!!!
yeah, it does at least have the "feel" of a DMA issue, but i'm not sure...
in any case, here's a DMA grep from my config, let me know what you think:
Code:
win32sux@andromeda:~$ cat /boot/config-2.6.17-10-generic | grep DMA
CONFIG_GENERIC_ISA_DMA=y
CONFIG_ISA_DMA_API=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
# CONFIG_BLK_DEV_IDEDMA_FORCED is not set
CONFIG_IDEDMA_PCI_AUTO=y
# CONFIG_IDEDMA_ONLYDISK is not set
# CONFIG_HPT34X_AUTODMA is not set
CONFIG_BLK_DEV_IDEDMA=y
# CONFIG_IDEDMA_IVB is not set
CONFIG_IDEDMA_AUTO=y
CONFIG_SCSI_PDC_ADMA=m
# CONFIG_SCSI_PATA_OPTIDMA is not set
CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=1
# CONFIG_IEEE1394_SBP2_PHYS_DMA is not set
CONFIG_BCM43XX_DMA=y
CONFIG_BCM43XX_DMA_AND_PIO_MODE=y
# CONFIG_BCM43XX_DMA_MODE is not set
CONFIG_CARDMAN_4000=m
CONFIG_CARDMAN_4040=m
# CONFIG_SOUND_DMAP is not set
i'm also gonna try to post what my syslog looks like during a stutter...
The config seems OK, but there are settings that influence whether DMA works that do not have the letters DMA in the settings name - for example, on my old GA8-TRS350MT motherboard, chipset level support for DMA was only available after I recompiled a 2.6.14.3 kernel with all lines containing "IXP" (for the IXP300 chipset on the GA8-TRS350MT) and "ATI" (for the ATI chips on the board) active... That's the thing. You'll need to find out exactly which chipset your motherboard uses, and see that support for that chipset is present in your kernel.
In addition to having DMA enabled in the kernel, are you using the hdparm utility to turn it on? I have this in my rc.local starup file for each hard drive
Code:
/usr/sbin/hdparm -m16 -c3 -u1 /dev/hd?
-c3 enables 32-bit I/O transfers with sync. Note that his applies the the drive and not each partition, so use it with /dev/hd? and not /dev/hd?1.

i'll try and check, but i seriously doubt there isn't support in my kernel considering ubuntu tries so hard to cover all bases, plus the centrino chipset is everywhere...

i think as far as DMA is concerned, if that is indeed the cause, i'd expect it would be in relation to the wireless card or the centrino chipset, not the hard drive... but here's what mine looks like just in case:

hi guys! okay, i was finally able to get a glimpse of what my syslog looks like from the moment a stutter starts to the moment it stops... i've had to split it into two posts due to the size limit... here's the first part, the second part appears on the next post:
