Hello, I am running into the same problem over here. We got an embedded board with a AMD Geode LX800 and CS5536 companion chip and a Sierre Wireless MC8790 miniPCI Express modem (which uses USB only). The problem was discovered just recently since it will work fine for some time but due to constant dis- and reconnects we eventually triggered the problem. The kernel we run is basically 2.6.28.10 (included in OpenWRT 15916) with an upgrade sierra.c from v.1.3.2 to v.1.7.8 (as suggest to us by Sierra Wireless). When I remove the ehci_hcd and run on just ohci_hcd everything works just fine (except that I lose USB 2.0). If I can supply you with any more information on how to solve that problem I will be glad to help.
