It does, it's a FujitsuSiemens Server and has ERST-II (LSI Software RAID) along with AHCI.
Changing to the old ata driver solves the problem.

Any chance to get this problem fixed? I couldn't see lockups on another OS with NCQ in AHCI mode enabled. I'd ship such a disk to anyone who is willing to debug.It's difficult to fix something, until problem could be reproduced.
I understand!The machine lock @3.5MB/s was wrong, sorry. Not the HD was the culprit but an intermediate router... But still there is the problem that ZFS stalls if I use these drives with ahci, not with ataahci.
If you wish to send drive - my address is: Topol-2, b34, f150, Dnepropetrovsk, 49040, Ukraine. Phone: +380503622312. Do not use courier services, only regular mail. Ask for tracking number.
Can you use such a drive? I mean for yourself. If yes, then I'll ship it, but if you say "na, thanks, no such crap" then I don't want to waste your time and highly appreciated skills to bother with vendor-specific problems.
