From: Baptiste Jonglez Date: Sat, 15 Jul 2017 20:57:54 +0000 (+0200) Subject: x86: Fix xen serial console by removing conflicting PATA driver X-Git-Tag: v17.01.4~15 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=da0219ed9f990e5a951197c2c9c6a916d17109d1 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 (commits 296772f9 and b36e24f3). 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.
