According to topic11253, we try to fix those bug using source code form "http://community.qnx.com/sf/
wiki/do/viewPage/projects.bsp/wiki/AmdGeodeLxdb800".
But this source code is different with the release version in QNX 6.3.2.

The source code happen "reset timeout", when we mount/umount many times. But the release version don't happen.

Could you help us to add follow two lines in function "rtl_findphy" using release version:
MDI_ResetPhy (rtl->mdi, rtl->cfg.phy_addr, WaitBusy);
MDI_SyncPhy (rtl->mdi, rtl->cfg.phy_addr);
 
Or you can provide the source code of release version?

Thanks.
