Reboot into recovery #2
Comments

this is not a kernel related issue that you are having. i am able to get to recovery with the power menu without issue (just tested and confirmed working; built fresh last night). |
|
I didn't know where else to put it or how to contact you. |
|
flash the latest nightly (clear dalvik prior to doing so), if you are encountering an issue. |
|
When wiping dalvik cache, I got |
|
That issue in the latest repository is being worked on. Now install the latest non oc kernel from droidbasement: reboot, and you'll be good to go. |
|
I still have CM7 (the stable release) installed, the nightly failed to flash. You want me to flash that zip through CWR, reboot, and I'll be fine? |
|
Please use the forums on forum.cyanogenmod.com and/or XDA Gtablet forums for further support. Thank you. -pershoot |

The latest nightly will flash. It just errors out in the end (for kernel flash). Flash the kernel over it that i linked and reboot, and you'll be set. |
|
Okay, thank you |

commit a8170c35e738d62e9919ce5b109cf4ed66e95bde upstream. When calculating the INIT/INIT-ACK chunk length, we should not only account the length of parameters, but also the parameters zero padding length, such as AUTH HMACS parameter and CHUNKS parameter.

commit 12fed00de963433128b5366a21a55808fab2f756 upstream. When we get oplock break notification we should set the appropriate value of OplockLevel field in oplock break acknowledge according to the oplock level held by the client in this time. As we only can have level II oplock or no oplock in the case of oplock break, we should be aware only about clientCanCacheRead field in cifsInodeInfo structure.

(imported from commit v2.6.36-rc4-167-g995bd3b) Due to the overly intelligent design of HPETs, we need to workaround the problem that the compare value which we write is already behind the actual counter value at the point where the value hits the real compare register. This happens for two reasons: 1) We read out the counter, add the delta and write the result to the compare register. When a NMI or SMI hits between the read out and the write then the counter can be ahead of the event already 2) The write to the compare register is delayed by up to two HPET cycles in certain chipsets. We worked around this by reading back the compare register to make sure that the written value has hit the hardware. For certain ICH9+ chipsets this can require two readouts, as the first one can return the previous compare register value. That's bad performance wise for the normal case where the event is far enough in the future. As we already know that the write can be delayed by up to two cycles we can avoid the read back of the compare register completely if we make the decision whether the delta has elapsed already or not based on the following calculation: cmp = event - actual_count; If cmp is less than 8 HPET clock cycles, then we decide that the event has happened already and return -ETIME. That covers the above #1 and #2 problems which would cause a wait for HPET wraparound (~306 seconds).

commit 4ff67b720c02c36e54d55b88c2931879b7db1cd2 upstream. This patch replaces the earlier patch by the same name. The only difference is that MAX_PASSWORD_SIZE has been increased to attempt to match the limits that windows enforces. Do a better job of matching sessions by authtype. Matching by username for a Kerberos session is incorrect, and anonymous sessions need special handling. Also, in the case where we do match by username, we also need to match by password. That ensures that someone else doesn't "borrow" an existing session without needing to know the password. Finally, passwords can be longer than 16 bytes. Bump MAX_PASSWORD_SIZE to 512 to match the size that the userspace mount helper allows.

To put it simply, It doesn't work. There's no way to get into recovery without Vol + Power. It doesn't work from the power > reboot option, doesn't work from ROM Manager.
