Subject: 2.6.14-rc4-mm1 and later: second ata_piix controller is invisible
Date: Tue, 25 Oct 2005 11:56:46 +0200 [thread overview]
Message-ID: <20051025095646.GA24977@roonstrasse.net> (raw)
Hi Andrew,
since 2.6.14-rc4-mm1, my second ata_piix (SATA) controller does not
show up in dmesg, effectively hiding /dev/sdb. 2.6.14-rc2-mm2 and
older (with the same kernel config) were ok, the same for Linus'
kernels: 2.6.14-rc5 without -mm1 has /dev/sdb, too.
0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150
Storage Controller (rev 02) (prog-if 8f [Master SecP SecO PriP PriO])
0000:00:1f.2 0101: 8086:24d1 (rev 02)
This PCI device (on-board on an Asus P4 mainboard) has two SATA
connectors, showing up as ata1/sda and ata2/sdb.
dmesg from 2.6.14-rc5:
libata version 1.12 loaded.
ata_piix version 1.04
ACPI: PCI Interrupt 0000:00:1f.2[A] -> GSI 18 (level, low) -> IRQ 177

Need more information? I could try to disable a few patches from your
-mm series if you name some.. it's too hard for me to guess which one
could be responsible for the breakage.
