Update: custom amd64 kernels with reduced set of devices work. Tested RELENG_6 and HEAD both SMP and UP. Should I try to find a pair of kernels similar one to another, one of which would work and another wouldn't? I've also discovered that it looks like isp driver in RELENG_6 is not safe with more that 4Gb of RAM. Under moderate load with 6G I get "isp0: deferred dma allocation not supported" which leads to various errors and finally to kernel panic. The same load never created problems with hw.physmem=2g and hw.physmem=4g under RELENG_6 and with 6G under HEAD. -- Oleg Sharoiko.
