Subject: [Bug] Boot hangs with 2.6.39-rc[123]
Hi list,
Apparently all the 2.6.39-rc kernels up to current git HEAD hang on my setup
here during boot. They survive the initramfs step, but after or during the root
file system mount it just hangs.
This is a software RAID-5->LVM setup. The machine itself boots without
any problems with a 2.6.38 kernel.
The hardware:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 1
model name : Intel(R) Pentium(R) 4 CPU 1.70GHz
stepping : 2
cpu MHz : 1699.523

hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pebs bts
bogomips : 3399.04
clflush size : 64
cache_alignment : 128
address sizes : 36 bits physical, 32 bits virtual
power management:
I hooked up a working serial console to capture the boot messages...
As I said initramfs and kernel loads fine it also enters runlevel "S"

Here the mount hangs. It does show /dev/root ... Done but since I use
concurrent mounts I think the done is from an earlier task.

This problem started somewhere between 2.6.38 and 2.6.39-rc1 but due to
the fast number of commits bisecting everything would take a long time.
I am thinking of only bisecting the block or dm layer but maybe someone
has a better idea or a fix already. :)
Please tell me if you need additional information about my setup, etc.
Kind regards,
Michael Guntsche
