Did this start happening recently, or has this always
happened on this system no matter how old the ACPI-enabled
Linux kernel is.

Please verify that you're running the latest BIOS.

Please try the latest ACPI code, available in 2.6.14-rc1
to see if it makes any difference.

Please attach the output from acpidump, available in the latest pmtools.

We need to see the acpidump for this machine.

acpidump file

ACPI dump (acpidump from pmtools util) file from kernel 2.6.14-rc2
Comment 4 Dalibor Horinek 2005-09-30 06:14:02 UTC
With kernel 2.6.14-rc2 it still do the same and it was occured first time, when
I start work with irda, /sbin/setserial and /dev/ttyS0
Comment 5 Robert Moore 2005-09-30 16:18:59 UTC
CSTX does in fact not exist, so the error seems to be valid. There also seem 
to be no SSDTs on this machine where the CSTX object could be hiding. For 
compatibility, it would be interesting to know what windows does with this.
Comment 6 Dalibor Horinek 2005-10-02 03:09:55 UTC
Ok, how can I know, what windows do with this? I don't like the "system" so
much, so I don't know, how to know it :))
Comment 7 Robert Moore 2005-11-17 11:05:26 UTC
There seem to be a couple of serious errors in the BIOS, we are still 
Comment 8 Lin Ming 2007-09-26 01:58:33 UTC
Please use the latest acpidump, available in the latest pmtools.

And attach the output from acpidump again.
