Thank you for your reply. I'll try the latest 2.6.16.13 kernel and see
how that goes.

I'll also try the kernel 2.6.17-rc3 as Andrew asked me to check if the
"Assertion failed!" message is gone in that release.

Thanks!

I believe quite some bits changed in sata between 2.6.16 and 2.6.17-rcX.
I assume your sata_mv.c will not work at all on anything else than
2.6.16(.xx) ?


Btw, building raid5 over the first eight disks works fine (76% done
now). Building raid5 over the last four disks fails immediately (drives
get marked F in /proc/mdstat).

The message "PCI ERROR; PCI IRQ cause=0x40000100" gives no result in
Google. Could this be a broken or miss-seated controller?

	With kind regards, Sander
