Make sure all the firmware is up to date. I've had an IBM x3550 M3 and it couldn't even boot a Windows 2008 R2 64 bit CD with the firmware it shipped with.
That seems like a useful tip, but do you know what exactly I need to
install and where to find it? I'm looking at an IBM download page right
now, but it's a little confusing - I can't seem to find anything that
it's obviously the *system* firmware, only entries like "Firmware for
Rack& Tower LCD UPS" and " Firmware for Local Console Manager".

What's the model and type? It should be xxxx-yyy where x can be 0-9 and y can be 0-9& A-z. You can find it on the front of the chassis.

Search for UEFI firmware. Those IBM servers don't have a classic BIOS anymore, they are EFI based. I looked it up following your model/type and found the updates.

Ah. Thanks.
I believe I missed that file because I searched for operating system
independent components (because firmware doesn't use the OS, right?),
but apparently I should have chosen some Linux variant instead.
I should perhaps mention that I found a solution, sort of: It seems like
the problem is that the system simply won't boot from a single hard disk
set up as just that - a single, separate drive. I suspect this has
something to do with the disk/RAID controller firmware, but updating it
did not help. If, on the other hand, I define (from within the
controller setup screen) a "RAID" containing only one drive, everything
works just fine...
Try nodmraid on the kernel line in grub - I needed this after one of
the upgrades in the 5.x series.
