Bug#414714: linux-image-2.6-686: SATA disk appears both as hdg and sda on VIA motherboard with JMicron controller
Package: linux-image-2.6-686
Version: 2.6.18+6
Severity: important
I have a VIA motherboard with a JMicron SATA controller. A quirk
settings in the kernel enables both the IDE and SATA interface to the
controller. As a result, my hard disk appears both as /dev/sda and
/dev/hdg. I access the hard disk using /dev/sda with linux 2.6.18-3, but
the dmesg gets filled with errors about failed accesses to /dev/hdg,
e.g.
end_request: I/O error, dev hdg, sector 625142272
end_request: I/O error, dev hdg, sector 0
end_request: I/O error, dev hdg, sector 8
end_request: I/O error, dev hdg, sector 16
end_request: I/O error, dev hdg, sector 24
end_request: I/O error, dev hdg, sector 32
end_request: I/O error, dev hdg, sector 40
end_request: I/O error, dev hdg, sector 48
end_request: I/O error, dev hdg, sector 56
end_request: I/O error, dev hdg, sector 0
even though it's not being accessed directly (maybe HAL?).
With Linux 2.6.18-4, the ide driver seems to be more aggressive, and it
manages to grab the interface from the sata subsystem, causing the hard
disk to be inaccessible via /dev/sda, and only working via /dev/hdg.
Since the system is set up to use /dev/sda (right from the root= command
line, but also fstab etc), this causes all sort of problems.
I cannot disable the ide modules completely because I have an IDE burner
attached to the main IDE interface (hda), so I've tried to disable
access to the ide2 and ide3 interfaces with boot parameters: this was
completely unsuccessful because all ide2=noprobe, hdg=noprobe, hdg=none
or ide.<same combinations> are totally ignored, the ide2 interface is
brought up and the hdg device appears.
