Summary: The boot process freezes and needs keyboard input to
continue - Bisected to Commit 988888c, bootup hangs
Product: Platform Specific/Hardware
Version: 2.5
Kernel Version: 2.6.36-rc1
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: x86-64
AssignedTo: platform_x86_64 at kernel-bugs.osdl.org
ReportedBy: Larry.Finger at lwfinger.net
Regression: Yes
My x86_64 system with an AMD Turion 64 X2 TL-60 CPU pauses/freezes as soon as
the kernel is loaded during boot. It will only proceed if some key is pressed
and stops many times. I have never stayed with it, thus it may run OK once
booted.
The problem was bisected to:
commit 9d8888c2a214aece2494a49e699a097c2ba9498b

x86, cpu: Clean up AMD erratum 400 workaround
Remove check_c1e_idle() and use the new AMD errata checking framework
instead.
