Dear sir,

Did it used to work before in Dapper or Edgy? Do you have the driver compiled and installed? If yes, what kind of driver? Or maybe, you use the driver included in kernel?
Zydas 1211 may have some troubles when it's used with SMP enabled kernels, like this generic kernel you use, so please, if it's possible, try to install i386 version of the kernel and post results.

Best regards,
Никола Милинковић

Hi,

It worked in Edgy with 2.6.17-10-generic.

On Feisty, it is using the driver installed by Ubuntu (I guess zd1211rw, as that's what was used previously).

I will try the 386 kernel.

Unfortunately, this system suffers from <https://launchpad.net/bugs/75052> (raid/LVM root FS), so booting any Feisty kernel is problematic, and it will not boot -386 at all 'cannot find /sbin/init' or similar (even after running scripts/local-top/mdadm from the initramfs shell).

I booted 2.6.19-7-generic, which does not crash on USB insertion of the device, and the device works fine (albeit only at 11Mb/s), once you get network-manager out the way (which is also broken wrt to this device <https://launchpad.net/bugs/72723>.

Sorry not to be more helpful,

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
