x86: Fix xen serial console by removing conflicting PATA driver
The Xen serial console has been broken since the xen_domu subtarget was merged in the generic x86 subtarget (commits1d6879ee
and371b382a
). The reason for the broken serial console seems to be an IRQ conflict between the serial console driver and the PATA_LEGACY driver: [ 1.330125] genirq: Flags mismatch irq 8. 00000000 (hvc_console) vs. 00000000 (platform[pata_legacy.4]) [ 1.330134] hvc_open: request_irq failed with rc -16. [ 1.330148] Warning: unable to open an initial console. Just drop the PATA_LEGACY driver from the x86/generic and x86_64 subtargets, since this driver is marked experimental and only supports very old ISA devices anyway. It is still included in the x86/legacy subtarget where it rightfully belongs. Fixes: FS#787 Signed-off-by: Baptiste Jonglez <git@bitsofnetworks.org>
