Hmm, the patch is from Oct, 6. The Beta 3 came more than 4 weeks later.
Why isn't it already applied? Are the any drawbacks with other Kernel-Parts?
The other thing, that makes me a bit confused is the need of twiddling
around with Kernel-Memory parameters. Maybe, the default values of 384MB
seem to be a bit less as ZFS does a lot of caching in RAM. But, why
breaks this up the system?
Less memory may lead to a performance penalty (even to very low values)
but should never made the system reboot or make it halt with a "kmem_map
too small"-Message - or am i wrong?
But we're in the experimental phase - so, I'll apply the mentioned patch
and test it again. Thanks.
