Bug Description

I use a Lenovo 3000 N100 laptop with a BCM4310 UART PCI Express card (pci-id 14e4:4312, rev 01). When using ndiswrapper the card works ok. Using it with the native driver causes the touchpad to go unstable (it sometimes goes to the point when it locks up, getting normal only after switching to another vt and back, but usually just locks/hops/random clicks for several seconds every couple of minutes) when trying to actually *use* the card (i.e. connect to a network, do a scan, transfer something). The card more or less works (it is unstable as well, but not as much as the touchpad). Last time during test unloading the module for about third time without reboot caused an oops and froze the system.

I will attach some logs and pci -nvv output.

This is the log. I have configured the interface for my WEP before. The instabilities occur with WPA as well (I have successfully connected with WPA/Network Manager at my friends, but the system was unstable. Regretfully I don't have any logs from that time)

Well, I'll just note that on 10.27 the issue is still present.

Bug #61388 claims to be solved, seems a bit different (like, similiar but not the same), and here it persists with 2.6.20-12.19...

I believe I have the same issue, when the issue arises I get the following in dmesg:

 TouchPad at isa0060/serio4/input0 lost sync at byte 1

I believe this is a duplicate of Bug #12124

It is similiar and quite probably both bugs are related to some buggy irq/other resources assignment. But I would consider a wireless/touchpad and USB/touchpad to be related but separate bugs, related either to the wireless card and USB controller or to the BIOSes of both laptops

Anyway, I suppose I have a bigger problem because some time ago I had a similiar problem with reading audio-cds (normals work). I'll try to reproduce it at some time.

On linux-image-2.6.22-3-generic 2.6.22-3.9 on gutsy the problem gets both worse and better: ndiswrapper doesn't work anymore (I don't know why), but I can effectively work using the bcm43xx driver. Still, there *are* problems when connecting (I'm using WEP) and then, after periods of stability, the mouse gets chunky again, then gets stable. Sometimes this causes the touchpad to loose some of its features (i.e. touchscroll), but logging in and out helps.

No system crashes this time.

Likely we wont be able to do much here. bcm43xx is still a work in progress.

As for ndiskwrapper, make sure you have linux-ubuntu-modules-2.6.22-3-generic installed (installing linux-image-generic should bring it in).

Without that, I wouldn't be able to use ndiswrapper at all. In my case, ndiswrapper loads and binds the interface, but NetworkManager fails to configure it.

As for bcm43xx - *sigh*, back to the big wait, then.

I just installed hardy and 2.6.24-1-generic. With the b43 driver everything works. I had to clean up a bit (removed /etc/udev/rules.d/70-persistent-net.rules line becaused it clashed with the old setting somehow) and it works perfectly.

I had the same issue with a new HP Pavilion dv6605us laptop, running gutsy. Compiling the b43 driver from linuxwireless.org, for the gutsy kernel, fixed the problem.

Hardy includes the b43 driver instead. Is anyone seeing this problem on Hardy?

Changing to "Fix Released", since the newer b43 driver doesn't show this problem. If anyone still has problems, please reopen the bug.
