I have set up a machine for testing purposes. Thinkpad X200 with

Kingston 60GB SSD, SV300S37A60G. I'm using a 3GB partition near the start
of the disk, on which I installed Haiku. I am trimming the boot volume,
without other activity happening.

So far I have not managed to corrupt the drive this way. However, the

trim command will time out. The HDD led stays on for some time, but then
the command is aborted.

{{{
port reset: port 0 undergoing COMRESET
ExecuteAtaRequest port 0: device timeout
sata_request::abort called for command 0x06
trim failed (64 ranges)!
}}}

Found out that I still have that particular SSD around (now in a different
machine). Same problem still happens as of hrev54949 (after re-enabling
trim support in the AHCI driver).

I increased the timeout from 20 to 2000 seconds (just in case the problem
was indeed that we didn't wait long enough). It stil timed out, and then I
got a KDL, null pointer dereference in BFS BlockAllocator::Trim.
