Description Teej 2010-09-05 14:44:38 UTC

In Gentoo, I ran "genkernel all" to compile the kernel and all modules and the following error occurred:

  CC [M]  drivers/scsi/ipr.o
drivers/scsi/ipr.c: In function 'ipr_mask_and_clear_interrupts':
drivers/scsi/ipr.c:653: error: implicit declaration of function 'writeq'
make[2]: *** [drivers/scsi/ipr.o] Error 1
make[1]: *** [drivers/scsi] Error 2

Comment 1 Teej 2010-09-05 14:45:13 UTC

Note: This is the 2.6.34-gentoo-r1 kernel for ppc

Comment 2 Rolf Eike Beer 2010-09-06 11:56:17 UTC

This sounds very familar: https://bugzilla.kernel.org/show_bug.cgi?id=16971

Is this a regression from earlier releases?

Comment 3 Teej 2010-09-06 13:31:17 UTC

That does look very similar to this problem, but of course in another driver. Strangely, that is also ppc.
I have also had the same error in the 2.6.35-r5 kernel sources in Gentoo, so this hasn't since been noticed/fixed and has in fact regressed.

The problem in the IPR driver is fixed with this patch:
