I'm running Linux 3.2 on a MIPS 34K with two VPEs (in MT_SMP configuration). It works fine in UP but with SMP it deadlocks during bootup (both CPUs gets idle). Typically like this:
[ 0.090000] CPU revision is: 01019550 (MIPS 34Kc)
[ 0.090000] Primary instruction cache 32kB, VIPT, 4-way, linesize 32 bytes.
[ 0.090000] Primary data cache 32kB, 4-way, PIPT, no aliases, linesize 32 bytes
[ 0.170000] Brought up 2 CPUs
<No more output>
I have tried to enable __ARCH_WANT_INTERRUPTS_ON_CTXSW but that didn't improve anything. Anyone else got this running or have any thoughts about what the problem may be?
Best Regards
