Ah shoot, I should know better than to respond after having a few beers. As Robert pointed out, modules are absolutely not supported in PAE kernels. That not only includes sym and usb, but also acpi (which is automatically loaded at boot). If you still want to experiment with the sym driver, just delete the line that the compiler complains about (it's in a code path that will likely never be used).

Ok I've now got problems with the compiled kernel, I get panics on my multiple cpu machine on boot just after boot & before the prompt is reached. It's a lock on cpu #2 ( I believe cpu 3 ).
Unfortunately I don't have the exact message nor do I have a kernel dump as this machine is "meant" to be a production one and as such a boot of kernel.old was done.
Does anyone have a 4 or greater cpu machine running 5.1-RELEASE succesfully ? I've got a 5.1-RELEASE machine running with the same kernel config & 2 cpu's without any problem so I can only think that it's something to do with more than 2 cpu's.

Hi All,
When trying to compile a kernel for my 8 cpu DELL 8450's I recieve an extremly puzzling error, I get a bunch of errors when compiling a kernel that has the following options in it...
options WITNESS
options NETSMB
options NETSMBCRYPTO
options LIBMCHAIN
options LIBICONV
options PAE
options SMP options APIC_IO
Without PAE SMP or APIC_IO the kernel will compile fine. With these
options I get the following error when compiling the sym scsi driver.

This is rather unfortunate as the only disks I have run off this controller. I've found that it does compile with the ahc driver but even then some usb stuff needs removing.
Does anyone have any insight into this and what I can do to get it fixed.
Cheers,
The key kere is likely PAE, not APIC_IO, as PAE changes the size of some data types. The USB problem is known. The sym problem looks to be harmless assuming that the warning you got is the only one that is emitted. However, it appears that it was never certified as being ready for PAE. If you're adventurous, you can try compiling and loading it as a module (warnings when compiling modules are not fatal like they are in when compiling the kernel).
If there are more errors/warning that what you list, I'd be interested in seeing them.
Scott
There are no other errors apart from those listed so I may try compiling as a module that gets loaded on boot. Just one problem, I succesfully build an SMP kernel without PAE and then rebooted and the server is no longer responding, it seems it crashed just after coming up as I was able to ping it 5 or 6 times and then it went away again. If I've got a crash dump I'll post it.
Cheers,
