Kernel DDB doesn't work in VM ?
I have kernel configured with options KDB and DDB. But when kernel panic occurs while running as VBox VM, VBox takes over and says: A critical error occurred while running the virtual machine, etc. It doesn't drop into DDB. Pressing Ok closes VM, pressing Ignore leaves it in hung state. sysctl debug.kdb.enter=1 also causes the above behavior as if panic has occurred. Is it possible to make DDB kick in while running as VM?

Re: [PATCH] Add 4K QUIRK for Intel X25-M, MARVELL SD88SA02 and OCZ Agility 2
Could you provide the output from camcontrol identify for these
disks I want to just double check the formatting before
commiting as I don't have these disks here in labs.
Regards
Steve

I think so but we need to act fast. Pools composed of affected disks will suffer from performance issues until they are reformatted with the correct block size. In addition, a certain benchmarking site, whose benchmarks are often fodder for trolls, uses the Intel X25-M in its benchmarks. Adding the quirk to 9.2 would eliminate an unfair handicap on FreeBSD from their next set of benchmarks. Actually I'm not 100% sure here: the current FreeBSD ZFS code does not handle stripesize at all, and thus if you create a pool with the patch, they will still be ashift=9. Justin (gibbs@) have a patchset to address this by the way, but since it's not yet in HEAD I wouldn't expect it be incorporated in 9.2...
