Recently one of my clients get a new (very cheap) P4VP-MX wich uses a VIA VT8235 Southbridge. This machine is not detecting (identify) ATA disk under 5.3. I have tested with 5.3-STABLE and 5.3-RELEASE, with 4.X it works. I tried with different disks and with CDROM, but nothing works. The same disk run on another machines (including a P4SP-MX wich uses SIS chipset) and 4.X run normaly. I have do some code debug, and ata_getparam() get no return (no interrupt is generated - ata_interrupt() never run). The workaround of PR/73706 not work for me (my secondary ATA also fail) and break another machine on tests. I'm playing with interrupt routing, but i cant get it working. Also tried with dma, acpi, pci.enable_io_modes and apic disabled. There is no error on dmesg until ATA_IDENTIFY timed out. Any ideas / workaround ? Thanks, Luiz
