Description Orion Poplawski 2007-05-09 22:01:28 UTC
Description of problem:

Logwatch reports:

--------------------- Kernel Begin ------------------------ 

 WARNING:  Kernel Errors Present
    rtc_cmos: probe of 00:06 failed with error -16 ...:  1 Time(s)
 
 ---------------------- Kernel End ------------------------- 

dmesg contains:

rtc_cmos 00:06: rtc core: registered rtc_cmos as rtc0
rtc_cmos: probe of 00:06 failed with error -16

Either:

- it's a kernel issue that needs fixing
- a kernel message that really shouldn't be reported
- something logwatch needs to ignore.

This is on an old Dell Inspiron 4150.  Let me know if you need any more hardware
details.

Version-Release number of selected component (if applicable):
2.6.21-1.3116.fc7

Comment 1 Orion Poplawski 2007-05-09 22:08:10 UTC
Looks like some upstream work is being done: http://lkml.org/lkml/2007/3/7/78

Looks like a conflict between the old RTC driver (CONFIG_RTC=y) and the new
rtc_cmos module (CONFIG_RTC_DRV_CMOS=m).

Comment 2 Chuck Ebbert 2007-05-09 22:35:40 UTC
We should be using one or the other. (Looks like the patch was never submitted.)

Comment 3 Dave Jones 2007-05-15 18:50:36 UTC
This should be fixed in the latest builds. (3148 and above)

Comment 4 Orion Poplawski 2007-05-25 21:11:06 UTC
The rtc_cmos messages are gone.  I've now got:

drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

which I believe would have been provided by rtc_cmos.  Not a big deal I think,
but I thought I'd mention it.


Comment 5 Dave Jones 2007-09-24 19:34:41 UTC
There are two other bugs open for that problem (230935 and 274261)
Not entirely sure whats up with that yet.
