We have not been able to replicate the battery drain and random reboot issue that several users have reported after the ICS update and subsequent firmware updates.
As such we are looking for a few volunteers here to run a custom logging problem and report back their results. The system needs to have either the random reboot or battery drain issue and cannot be rooted.
If you are willing to run this logging problem (very much appreciated) then please PM with the following information.

I will start sending out the logging file and instructions to the test group tomorrow.
The logging tool simply captures low level OS routines that might lead us to the source problem.

The logging tool was delivered to the first control group tonight. I will send the tool to the second control group tomorrow. Thank you for your assistance and replies.

Thank you for your assistance and log reports. R&D is working on them feverishly right now. I will send out the tool to a third control group shortly.

First off, thank you for your assistance and log reports. We are still investigating root causes for some of the problems. As such, personnel from the three control groups might be contacted directly for a system replacement so we can further investigate the lockup problem. I will have an update later this week.

Thank you for the continued log reports. We are working through all the data now within R&D and at NVIDIA/Google. As soon as I have word on a Firmware update I will post it here.

We sent out a beta Firmware release to a few users for testing. So far, it has solved the problems these users have experienced but I am still waiting on a couple of test updates. We also received back a unit that had the random lockup and screen corruption problem and so far after 22 hours of testing no problems. If the balance of the test updates are positive, we will get this build qualified and releases ASAP.

220.127.116.11 will roll out today in North America. This release addresses several of the random reboot and lock problems reported by a few users after upgrading to ICS. It also provides new functionality with WiFi-Direct, Unzip in File Manager, Restore Tab function in the Browser, and general performance/stability tweaks. Although we had a high success rate in the beta testing phase in solving the random reboots, there were a couple of users who still experienced it during deep sleep mode. We are having those systems returned to us for further analysis and regression testing with their particular setups.

We will release 18.104.22.168 into beta testing shortly. This firmware contains new NV code based upon the beta test group who still had issues with .21. I will provide updates once the firmware goes out to the beta group but it did fix returned units that experienced random lockups after .21.

I have been out with pneumonia but will have messages forwarded to the Customer Care Team. The .24 release is in final qualification testing and will be released shortly.
5/10/2012 Update -
The .24 release is approved and will be released in the near future.
5/14/2012 Update -
The .24 release should go to FOTA later today or early tomorrow. Please shutdown and perform a cold boot after updating.
5/15/2012 Update -
Bad news, Google has changed their CTS qualification requirements on firmware so the .24 release is delayed for a couple of days. We have asked for an exception to release earlier, especially since it already passed qualification testing.
5/16/2012 Update -
The .24 release should go to FOTA very shortly.
5/22/2012 Update -
Sorry for the delay, tried not to die from pneumonia last week after a relapse. I will start answering general questions again today and forwarding CSR events to the Service Team. Good news is that we have hired a full time employee to assist our Tablet owners in the Android centric forums. His name is Tien Phan and he is available here under the user name Asus_USA. He is part of our new Customer Loyalty Group and will be taking over forum coverage and assisting our valued customers. I will still be around, especially to handle technical problems and coordinate with Engineering until Tien is completely up to speed. However, as always, if you run into a problem that is not solved by our Service Group please feel free to contact me.

We are working on another release with updated code from NV/Google. I will be in Taiwan next week to discuss this version and once a beta is available we will release it to a small group of testers. So far, this updated code based has worked extremely well on the TF201/TF300 in beta testing. As soon as I have an update it will be posted.
6/11/2012 Update -
We received additional code enhancements from NV/Google while I was in Taiwan last week. We will create a beta update shortly for testing and hopefully the next firmware update will occur in the next two weeks. I/O and Thread priority changes are the top two items and will address ANR and Sleep issues, however, still testing various application loads as some applications do not want to play nice with thread overrides.
7/4/2012 Update -
New .27 Firmware is released and addresses browser and ANR problems among other items. As always, after the update is complete, clear browser and system caches, shutdown and then power up.
