Re: JMicron JMB363 PCI SATA/IDE Card Support

[Matthias Prager <linux@matthiasprager.de>]

I did some more digging and came up with a partial
workaround:
After adding the line:
>	{ PCI_VDEVICE(JMICRON, 0x236f), board_ahci_ign_iferr },
(at line 301 of drivers/ata/ahci.c)
The the sata ports of my two cards get detected and lspci -k shows
they are using the ahci driver.

My guess is the 'RAID bus controller [0104]' mode/class is keeping
my cards from beeing detected (they probably would be if they were
in PCI_CLASS_STORAGE_SATA_AHCI mode). Which would mean line 297
is just plain buggy.

This still leaves the problem of the missing IDE Ports (one master+slave
port per card are still not detected). I'm trying to
understand how the pata_jmicron driver is supposed to work
but haven't wrapped my head around it yet.
