No, I cannot reproduce it here. It seems that it requires a special GSM net situation. From the PCO2 logs you made, it look like this without applying the AT%SLEEP=2 workaround (Thank you for allowing to post this trace overview). All times are relative, CID is the cell ID: 00:06:04:667 MMR_REG_CNF received: LAC: 0020, CID: DACC 00:09:37:249 MMR_REG_CNF received: LAC: 0020, CID: DAB8 00:11:45:560 MMR_REG_CNF received: LAC: 0020, CID: 00CA 00:12:41:293 MMR_REG_CNF received: LAC: 0020, CID: C834 00:14:24:681 MMR_REG_CNF received: LAC: 0020, CID: DACC 00:14:48:234 MMR_REG_CNF received: LAC: 0020, CID: DAB8 00:15:23:502 MMR_REG_CNF received: LAC: 0020, CID: 00C0 00:16:22:414 MMR_REG_CNF received: LAC: 0020, CID: DACC 00:16:49:465 MMR_REG_CNF received: LAC: 0020, CID: 00CA It seems that you have at least five cells for your network around which can be received with a similar level. [ Hey, I think I have buy more BS-11 base stations and install all of them to get something similar here ;-) ] On a first look the cell re-selections are done because the GSM modem has decided that a different cell is better than the current one. I would say that this is not necessarily a wrong behavior of the GSM modem. The situation is similar with the AT%SLEEP=2 workaround applied: 00:03:44:457 MMR_REG_CNF received: LAC: 0020, CID: DAB8 00:03:58:336 MMR_REG_CNF received: LAC: 0020, CID: 00CA 00:04:32:477 MMR_REG_CNF received: LAC: 0020, CID: DACC (The trace is shorter so there are not that many cell re-selections). Is this a similar frequency of cell re-selections you see when Bug #1024 is occurring ? What image do you run on your phone ? I ask because I can see regular activity on the AT command interface. For example every minute the modem is asked about its SMS status (I wonder why the modem has to be polled and why the unsolicited status messages from the modem are not enough to find out if a new SMS has arrived). > I still have the option open to have PCO2 disconnected and try to get some > traces once the phone starts to show the bug. > Yes, this would be great if you could try it out.

Hopefully if gives some hints to what is going on.
