Description
Whenever I try to power on my antenna, I get the error "Modem power-up failed:
10". Also, if I try to manually register with the network, I get an error after
'AT+CPIN="...."'. I'd include additional log files, but I'm not sure what files
would be useful.

Any update on this annoying bug? Any intuition why it is failing?
In my experience, I use libgsmd-tool -m shell and use the O command to power up the antenna. Nondeterministically with probability about 0.9 (guess), it will fail and produce the error noted. With probability about 0.1, it will succeed. I just keep issuing the O command until it succeeds, which is usually after around 10 or so tries. After that, registration typically proceeds correctly.
I have device GTA02Bv5, firmware Moko8. I use OM2007.2 with the latest updates from opkg.

not sure if this is related to libgsmd or a general issue. if it's libgsmd specified then we should resolved as community.

I have since upgraded to OM2008.9 and this bug does not appear to be present in that distribution. Because OM2007.2 seems to be a buggy and dead distribution (although, one that for reasons unknown is still shipped with the phones), we might just want to recommend an upgrade to those affected, and close this bug.
I am also seeing this on my GTA02
