HPT366 not enabled by kernel 2.6.21.2

HPT366 not enabled by kernel 2.6.21.2

[Pascal Schmidt]

Hello!

I recently upgraded my kernel to 2.6.21 (.1 and .2 with identical
results) and my second IDE controller, a HPT366 on a PCI card,
doesn't get enabled any more. The latest previous kernel I used was
2.6.19.7, where the HPT366 worked.

Here's the HPT366 part of the 2.6.21.2 dmesg:

HPT366: IDE controller at PCI slot 0000:02:0a.0
ACPI: PCI Interrupt 0000:02:0a.0[A] -> GSI 18 (level, low) -> IRQ 18
HPT366: chipset revision 1
HPT366: using 33 MHz PCI clock
HPT366: 100% native mode on irq 18
HPT366: neither IDE port enabled (BIOS)
ACPI: PCI Interrupt 0000:02:0a.1[A] -> GSI 18 (level, low) -> IRQ 18
HPT366: using 33 MHz PCI clock
HPT366: neither IDE port enabled (BIOS)

There is a flash disk connected to the primary channel (master)
which also shows up in the controller's BIOS screen, so I don't
think it's true that both ports are disabled.

Under 2.6.17.9 the "neither IDE port enabled" message doesn't
happen and hde gets detected.

Please CC me on replies.

The fix from Sergei (queued for 2.6.21.3) is here:

http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=blob_plain;f=queue-2.6.21/hpt366-don-t-check-enablebits-for-hpt36x.patch;h=0833e0a37e23ed103a18ca93684201e1cb94a0a9

[ it has already been merged into 2.6.22 tree ]

Thanks,
Bart
