Dear Raghava, dear Linux folks,
Using a PMC Adaptec HBA 1000-8e with latest Linux, it only initializes
in sync mode, instead of async mode.
```
$ git describe --tag
v4.10-rc8-47-g0722f57bf
$ dmesg

```
Searching the vendor Web site, there is *Linux Driver Source
1.2.1-53005* available for download [1].
How does the upstream process work? Is there a git repository somewhere
from Microsemi? Are the patches already up for review? (I didn’t find them.)
The answers would be very helpful for our evaluation of the device.
Kind regards,
Paul
