Reassigning to linux, this is a bug in the driver code for that chip (it works in wpasupplicant, but that's probably just not excercising the right code paths to trigger the bug, which was done with kwlan. Perhaps it's something related to background scanning).

It has never worked stably with network-manager (since Ubuntu 8.10). In 12.04 alpha the network-manager even hangs so severely, that it can't be stopped. network-manager should include a black list for unsupported chips to keep the system usable. In my laptop the Marvell chip is connected to a SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 24) Drivers are sdhci sdhci-pci libertas libertas-sdio. The chip works perfectly with wpa_supplicant. (But in all older (K)ubuntus I have it used it may still be crashed when using throughput monitors like kwlan. Still need to verify this in 12.04 or has any progress been made?)
