PROBLEM: 3.8.0-rc4 keyboard failure at boot

[Brad Tilley]

1. Keyboard doesn't work at boot. Users are unable to enter cryptsetup dm-crypt decryption password at boot. 

2. Keyboard fails occasionally on some AMD multi-core systems. Users reboot those systems until the keyboard works. Normally only three to four reboots are required to get a working keyboard. 

2a. The keyboard *always works* on an Intel(R) Celeron(R) CPU 430 @ 1.80GHz. This is true for other single core systems as well. 

2b. The keyboard *never works* on an Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz.

3. Keywords: kernel, cryptsetup, keyboard, dm-crypt

4. Linux version 3.8.0-rc4-bb (rbt@bb) (gcc version 4.4.5 (Debian 4.4.5-8) ) #1 SMP Fri Jan 18 18:50:14 EST 2013

5. No oops message to send.

6. N/A

7. Standard desktop PCs using USB keyboards. Operating system is Debian Linux stable.

7.1 ver_linux from the system where the keyboard always works:

7.2 Intel(R) Celeron(R) CPU 430  @ 1.80GHz (keyboard always works)
    Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (keyboard never works)

7.3 Can send from kernel 3.7.3 upon request.

7.4 Can send from kernel 3.7.3 upon request.

7.5 Can send from kernel 3.7.3 upon request.

7.6 Can send from kernel 3.7.3 upon request.

7.7 Can send from kernel 3.7.3 upon request.

8. This problem occurs in 3.8.0-rc3 and 3.8.0-rc4. The ver_linux output above is from the computer where the keyboard always works, however the computer with the keyboard that never works runs the same OS (Debian Linux stable), and has the same build tools, very similar kernel config, etc. I'm unable to proceed past cryptsetup/dm-crypt on the computer that always fails with 3.8.0-rc4 (sorry). Kernel 3.7.3 works all the time on all the systems. It never fails. All the systems use dm-crypt/cryptsetup and have encrypted disks. I've updated the BIOS (on the systems they have no working keyboards) to the latest manufacturer version. I've used different keyboards in different USB ports (have not tried a PS2 keyboard). 

Please email me directly if you want more info. I can patch and report back if that would be helpful.

Thanks,

Brad
