[Debian] Kernel 3.12.9



	Hello,

I have several Sun Fire and Enterprise T1000. I have some trouble with internal SAS adapter. Some T1000 work fine with Fusion MPT SAS Host driver 3.04.18, some don't but perfectly run with older drivers.

I have tested all T1000 that don't run with 3.04.18 driver with SunVTS and hardware seems to run fine.

Last friday, a power supply was reported as defective and I have stopped all servers to maintenance. As all T1000 worked with 2.6.30.9 and 2.6.38 linux kernel, I have upgraded all installations.

Now, I'm trying to boot a T1000 with 3.12.9 linux kernel. I have tried debian binary package. Boot stops with : INFO: rcu_sched detected stalls on CPUs/tasks: { 0 2 3 4 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23} (detected by 5, t=5927 jiffies, g=18446744073709551319, c=18446744073709551318, q=1809) CPU[ 0]: TSTATE[0000000080001603] TPC[000000000042b5e8] TNPC[000000000042b5ec] TASK[swapper/0:0] TPC[arch_cpu_idle+0x80/0x8c] O7[arch_cpu_idle+0x6c/0x8c] I7[cpu_startup_entry+0xe8/0x168] RPC[start_kernel+0x37c/0x38c] CPU[ 1]: TSTATE[0000000080001602] TPC[000000000042b5e8] TNPC[000000000042b5ec] TASK[swapper/1:0] TPC[arch_cpu_idle+0x80/0x8c] O7[arch_cpu_idle+0x6c/0x8c] I7[cpu_startup_entry+0xe8/0x168] RPC[0x90ee58] CPU[ 2]: TSTATE[0000000080001602] TPC[000000000042b5e8] TNPC[000000000042b5ec] TASK[swapper/2:0]

I have tried to build my own kernel (with the same configuration I have used to build 2.6.38). Same result :

Allocated 64 Megs of memory at 0x40000000 for kernel
