Eheh, sorry for this :-).

You guessed right!
panic: kmem_malloc(114688): kmem_map too small: 775847936 total allocated
I think running a 64 bits kernel would help a lot in that case.
Unfortunately I don't think my CPU supports the instruction set:
CPU: Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz (1869.88-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x6f6 Family = 6 Model = f Stepping = 6
Features=0xbfebfbff<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,HTT,TM,PBE>
Features2=0xe3bd<SSE3,DTES64,MON,DS_CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM>
AMD Features=0x20000000<LM>
AMD Features2=0x1<LAHF>
TSC: P-state invariant
I will look into the wiki about ZFS tuning.
Thanks,
