Model and make is not anymore available, it was LDLC (website ldlc.com). It
must be very recent since they removed their products from the market. This
is something possible that they do have has dome problems with it.
The error actually appears wjile installing xfont46.tgz which is very very
slow. It is normal speed util that particular file .
errors : many "atascsi_atapi_cmd_done, timeout"
one "d0(ahci0:3:0): Check Condition (error 0x70) on opcode 0x28
SENSE KEY: Illegal Request"
The SSD appears in the bios as "Veritech SSD 2009-03"
Motherboard : Gigabyte GA-MA790X-DS4 F4
After quite a while, it finally finished the install process (passed the
various errors) but the boot on SSD drive fails and crashes.
Unfortunately, I am not used to extract from a machine that half works the
dmesg and kernel crash informations (using serial interface).
I have bought 2 cards (exactly identical) from the same supplier, and
actually one of them work in production on mye server, and the one on my
personal computer works fine with other operating systems (ex. Ubuntu).
