Hi,

I'm seeing a kernel hang at boot with the ALI15x3 driver on a Sony PCG-C1MV/M with 2.4.19-pre4-ac2.

The kernel hangs right after printing
ALI15X3: chipset revision 196
ALI15X3: not 100% native mode: will probe irqs later

After adding printk calls to alim15x3.c, it seems to hang during the pci_write_config_byte(isa_dev, 0x79, tmpbyte | 0x02) call on line 588.

The kernel successfully loads if I build without ALI15x3 support, printing these messages:

ALI15X3: chipset revision 196
ALI15X3: not 100% native mode: will probe irqs later
ALI15X3: simplex device: DMA disabled
ide0: ALI15X3 Bus-Master DMA disabled (BIOS)
ALI15X3: simplex device: DMA disabled
ide1: ALI15X3 Bus-Master DMA disabled (BIOS)
hda: IC25N020ATDA04-0, ATA DISK drive

Is the ALI15x3 driver falsely enabling udma on my system?

ide0=nodma doesn't help, either...

I'm appending the output from lspci -vv in case that helps.

Thanks for any help...

After adding printk calls to alim15x3.c, it seems to hang during the pci_write_config_byte(isa_dev, 0x79, tmpbyte | 0x02) call on line 588.

Does it work if you comemtn that line out ?

I had the same issue with my Lifebook P-2040. I found a patch on-line to work around the issue. I'll look for it and send you a link.

This problem is being addressed at ALI with the help of Sony. I can not tell you the issue because I have not been authorized.

After adding printk calls to alim15x3.c, it seems to hang during the pci_write_config_byte(isa_dev, 0x79, tmpbyte | 0x02) call on line 588.

Does it work if you comemtn that line out ?

No, if the line is commented out I get:

hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hda: drive not ready for command

. . . and then the kernel panics because it can't find init.

No, if the line is commented out I get:

hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hda: drive not ready for command

Translation the HOST is not setup and the enable hooks are broken. If you write to those bits it will tank the controller, and that is as much as I can come forward on at this point. This is appears to be exclusive to the TransMeta based NorthBridge + ALI south bridge.
