My sprint EX720 was updated to firmware 159/PRL 60751 about 2 weeks ago, and now I have nothing but problems. Before that is was fine.
Now, when I sleep, the computer sleeps. If I wake from sleep, work for a bit, then sleep again, it refuses to sleep (or restart or shut down) and there are log entries in the system log about the device being removed improperly.
I have a Dell M1330 with the EX720, running Vista Ultimate x64. When it gets hung up I have to do a hard restart, if I try to shut down it hangs on the “Shutting Down…” screen indefinitely. If I disable the cellular card in the BIOS, I can sleep all day, over and over with no problems.
Would love to know if anyone else is experiencing this. It’s a drag because I sleep my machine many times a day.
