Hi KML
I am installing gentoo 2007.0 (kernel 2.6.19) on a dual AMD Opteron server (total of 4 cores). The hard disk is a Stardom 2611-2S-S1 device: actually two 250GB drives in a RAID0 config managed by the device itself - it should appear to the kernel as one SATA drive. If it matters, the underlying HDs are "Seagate Barracuda 7200 10"s. Here's the device:
http://www.synetic.net/Synetic-Products/Stardoms/SR-2611-SA/Stardom-2611.htm
During the install and at different points in the process I get an "HSM violation" and the system becomes unresponsive. It looks like a similar situation to:
http://lkml.org/lkml/2007/6/6/195
Will more recent kernels work with this hardware (should I keep it and try the install again) or should I switch hardware to something more compatible (like an Adaptec card)?
Thanks!
Bryan

Please post full dmesg and full 'hdparm -I' result. Also, if possible,
please try 2.6.22.5. Even if it doesn't fix the problem, it would
report error conditions better.
Presumably in the week and a half between Bryan's report and your request,
Bryan has gone off and got an adaptec card. Bryan, it would be helpful if
you could rebuild the original systam and help us get to the bottom of this
bug, thanks.
I reported a very similar bug back a few releases ago.
Anyone who wants to try it themselves, can do this with hdparm-7.7 (from sourceforge):
hdparm --drq-hsm-error /dev/sda
Whether or not it hangs the machine does depend upon exactly which SATA LLD is used,
and what model/revision of drive is installed. But if it hangs for you (eg. Tejun),
then you now have a way to reproduce a HSM error "on demand" for testing. :)
Cheers
