Thanks for your help, God :)
Here is the call trace in symbolic form. This particular oops came very early (while booting), sometime i am able to use 2.1.8 for 5 - 10 minutes.
ksymoops is suposed to give the call trace automagically, but mine don't :( (libg++2.7.2.1)
c01259a5 - unlock_buffer c01a6313 - end_scsi_request c01a67e9 - rw_intr c01a2ac4 - scsi_done c01ae685 - ncr_complete c01ae6aa - ncr_complete c01ae70f - ncr_wakeup c0111680 - timer_bh c01ad621 - ncr_intr c01b1753 - ncr53c8xx_intr c010c8ca - do_fast_IRQ c010c391 - fast_IRQ12_interrupt c0109654 - sys_idle c010a7e8 - system_call c0109348 - init c01091c3 - start_kernel c01c5e5d - _etext c0116c08 - it_real_fn
Lots of ncrBsd stuff, I didn't supposed ncrBsd to be guilty since I was using the same version (1.14b) with 2.1.7 without any problem.. I change my mind. On one of my 2.1.8 compile, I had applied the patch 1.14b -> 1.14c, but it still oops & crash.

Ok ok, i will sleep better :)

Sure i will, but first i will recompile 2.1.8 with ncrBsd trimmed down (5MHz sync, 4 tag/queue)
