Dear all,
Here is ALi M5451 audio's patch file. In this new release ,version 0.14.8, we've
made such modifications.
1, Set EBUF1 and EBUF2 to still mode to avoid that upon some platforms the audio
will stop after playing for a while.
2, Reset m5451 controller to avoid ac97 access timeout

Writing a device driver for a IO card, I have the following message from
the kernel:
Unable to handle kernel paging request at virtual address 000d0804.
[then it gives the register values]
Segmentation fault."
This address (0xd0804) is the location of a "mailbox" reserved by the IO
card, and

That's the thing I wanted to work around, but ok. It was just a

Here is the patch against the buggy Cypress RTC which is found on some
Alpha boards. It's tested with 2.2.16 & 2.2.19 kernels and as seems should
work with 2.4.x kernels. This patch differs from initial Ivan's version by
the "cc" variable type & different calibrate divisor usage for better

I have no problem with the idea of a function to indicate which I/O maps you
are and are not using. But passing
