Well, I've seen nothing more than the 82801DB (which was listed in lspci). So maybe there is no HRNG :( This leaves the main problem, which is the lack of entropy. Does anyone have an idea on how to solve this problem ? It appeared with recent kernels. For ex, 2.6.8 had an entropy pool always > 3000, while 2.6.18 and other recent kernels show ~ 150. # sysctl kernel.random.poolsize kernel.random.poolsize = 4096 # sysctl kernel.random.entropy_avail kernel.random.entropy_avail = 196 This is really annoying, since the box should also use SSL/TLS operations, and it will be real slow ..
