To make a very long debugging story short, I think there is an issues/bug
with the mvsas driver. It works, with older kernels, and breaks on
newer kernels.
My Debian Jessie system was running great on a 3.18 kernel. Changed
cases to a newer supermicro case with a SAS expander backplane (SAS933EL). That
was the only hardware change. Now, when ever I boot, the system kernel panics.
3.2.65-1+deb7u2 works
3.9.0 Gentoo CD works
3.16+ all fail
Attached are 3 kernel panics on 3.16+ kernels.
Motherboard is a Supermicro X8SIE, with a "Marvell Technology Group Ltd.
88SE6440 SAS/SATA PCIe controller"
Is this a known bug?
At this point I have two options:
Stick with the old kernel (yuck)
Buy a new card running a better supported chipset
Any help would be greatly appreciated
Thanks
