 Posted: Wed Feb 13, 2013 6:14 pm Post subject: [Solved] Cannot access the Hardware Clock via known method. |
 |
|
After installation and compiling the genkernel 3.6.11 with (almost) the default config, like this
| Code: | | genkernel --menuconfig --install all |
i get:
| Code: | | Cannot access the Hardware Clock via any known method. |
In the boot sequence. The only things i changed to the default config are
| Code: | Processor family (Opteron/Athlon64/Hammer/K8)
Preemption Model (Voluntary Kernel Preemption (Desktop))
Timer frequency (250 HZ) |
and i deactivated the file systems i do not need. The kernel itself works, btw, without any problems, and the boot sequence did not show any other errors.
Now, i have looked at some other threads here, but the do not seem to solve my case:
https://forums.gentoo.org/viewtopic-t-931142-start-0.html
https://forums.gentoo.org/viewtopic-p-6991198.html
The strange thing is that i have activated the RTC:
| Code: | fret ruud # grep CONFIG_RTC /etc/kernels/kernel-config-x86_64-3.6.11-gentoo
CONFIG_RTC_LIB=y
CONFIG_RTC_CLASS=y
CONFIG_RTC_HCTOSYS=y
CONFIG_RTC_HCTOSYS_DEVICE="rtc0"
# CONFIG_RTC_DEBUG is not set
CONFIG_RTC_INTF_SYSFS=y
CONFIG_RTC_INTF_PROC=y
CONFIG_RTC_INTF_DEV=y
# CONFIG_RTC_INTF_DEV_UIE_EMUL is not set
# CONFIG_RTC_DRV_TEST is not set
# CONFIG_RTC_DRV_DS1307 is not set
# CONFIG_RTC_DRV_DS1374 is not set

# CONFIG_RTC_DRV_S35390A is not set
# CONFIG_RTC_DRV_FM3130 is not set
# CONFIG_RTC_DRV_RX8581 is not set
# CONFIG_RTC_DRV_RX8025 is not set
# CONFIG_RTC_DRV_EM3027 is not set
# CONFIG_RTC_DRV_RV3029C2 is not set
CONFIG_RTC_DRV_CMOS=y
# CONFIG_RTC_DRV_DS1286 is not set
# CONFIG_RTC_DRV_DS1511 is not set
# CONFIG_RTC_DRV_DS1553 is not set
# CONFIG_RTC_DRV_DS1742 is not set
# CONFIG_RTC_DRV_STK17TA8 is not set
# CONFIG_RTC_DRV_M48T86 is not set
# CONFIG_RTC_DRV_M48T35 is not set
# CONFIG_RTC_DRV_M48T59 is not set

# CONFIG_RTC_DRV_BQ4802 is not set
# CONFIG_RTC_DRV_RP5C01 is not set
# CONFIG_RTC_DRV_V3020 is not set |
But it does not seem to work:
| Code: | fret ruud # zgrep CONFIG_RTC /proc/config.gz
# CONFIG_RTC is not set
# CONFIG_RTC_CLASS is not set |
Checking that the config is indeed copied:
| Code: | fret ruud # md5sum /usr/src/linux/.config ; md5sum /etc/kernels/kernel-config-x86_64-3.6.11-gentoo
5eac857868287aeb19b30882353d8048 /usr/src/linux/.config
5eac857868287aeb19b30882353d8048 /etc/kernels/kernel-config-x86_64-3.6.11-gentoo |
and used:
| Code: | fret ruud # ls -la /usr/src/linux/.config
-rw-r--r-- 1 root root 95222 Feb 13 17:33 /usr/src/linux/.config
fret ruud # ls -la /boot/kernel-genkernel-x86_64-3.6.11-gentoo
-rw-r--r-- 1 root root 2647392 Feb 13 17:40 /boot/kernel-genkernel-x86_64-3.6.11-gentoo |
I further tried to set in menuconfig
| Code: | | [*] HPET - High Precision Event Timer |
but it did not make any difference.
What could be wrong here? (I have the feeling the symbol CONFIG_RTC itself is missing, but how is that possible.)

Try:
| Code: | genkernel --menuconfig --clean all
In menuconfig hit /
Search for CONFIG_RTC |
and then | Code: |
Device Drivers -->
[*]Character Devices -->
[*]Enhanced Real-Time Clock Support |
--install is not a genkernel option btw...

Interesting. the option you describe is only present if i disable
| Code: | Device Drivers --->
[*] Real Time Clock ---> |
This then also brings the CONFIG_RTC back.
I am compiling the kernel now, tomorrow w'll see if it works.
| Quote: | | --install is not a genkernel option btw... |
Well i did not make it up myself, look at
http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?full=1
and search for '--install'. It does what it promises (install in boot) 
Thanks so far! |

Okay, this is driving me nuts! Changed as suggested, build the kernel and ... same problem!
So:
| Code: | fret ruud # grep CONFIG_RTC /etc/kernels/kernel-config-x86_64-3.6.11-gentoo
CONFIG_RTC=y
# CONFIG_RTC_CLASS is not set |
But:
| Code: | fret ruud # zgrep CONFIG_RTC /proc/config.gz
# CONFIG_RTC is not set
# CONFIG_RTC_CLASS is not set |
WTF: Why is This setting not Followed? I checked that the new kernel was indeed installed in boot, and i rebooted!
How can this be? I used this:
| Code: | | genkernel --menuconfig --install --clean all |
and subsequently changed the option. Must be some dependency:
| Code: | Symbol: RTC [=y]
│ Type : tristate
│ Prompt: Enhanced Real Time Clock Support (legacy PC RTC driver)
│ Defined at drivers/char/Kconfig:285
│ Depends on: !RTC_LIB [=n] && !PPC && !PARISC && !IA64 && !M68K && !SPARC && !FRV && !ARM && !SUPERH && !S390 && !AVR32 && !BLACKFIN && !UML
│ Location:
│ -> Device Drivers
│ -> Character devices
|
but which one? I do not see an obvious candidate. Or is it IA64 (i am on amd64)?
I am getting the feeling building a Gentoo kernel clean out of the box is getting a more and more difficult task every year. The last nine or so times i tried (in approximately two years) only one of them was completely trouble free. And in one case i never got it running at all. And these were clean installs! (I stopped doing major upgrades some time ago since it was giving me to many problems.) |

Did you observe the kernel being compiled after changing its config? Does the timestamp in `uname -a` match the time you ran genkernel? |

devlaam,
paste back ls -l /boot/ and uname -a

Guys,
It seems i am getting to old for this kind of stuff .... 
Installing in /boot is fine, but if i forget to mount /boot that does not help a lot. I checked only if the build kernel was of later date than the config file, which was so. Of course i should also always check if that kernel is also running after boot. Sigh ....
The solution you presented works. Apologies for wasting your time! |
