SCSI Probe Problem

[Tony Holmes]

Hi!

I have a server running 4.9-STABLE that I updated to 4.10 so that I could
use a Promise TX-S150 to mirror a pair of SATA disks (seagate). The system
currently has 4 SCSI drives on an Adaptec 19160 working flawlessly in them.
Prior to the upgrade, the Promise controller and disks were installed,
the disks configured in the promise controller and all was fine, except the
kernel didn't recognize it, hence the reboot.

Initially, I attempted an upgrade to a later 4.9-STABLE and on Friday, to
4.10-RELEASE.

In both cases, the boot sequence hung at the SCSI reset (waiting for 15 sec)
on the newer kernels. The new kernels were GENERIC with HZ set to 2000
and quotas turned on.

Due to the fact that it is a production system, I could not debug further
and reverted to the older kernel (with the new world) and it's running
fine.

Has anyone else experienced this?

I noticed no details of any issues with the ahc driver or other issues in
the UPDATING, so this perplexes me a litte.

I assume that to aid I will have to eventually go in, install the new
kernel and boot -v with a paste, but need to do it in the wee hours
and warn my customers.
