 |
|
Hi,
I have a laptop running gentoo and I have just upgraded my kernel from 2.6.22-r9 (I believe the best kernel performance) with 2.6.25-r7.
When doing a restart, 3 out of 4 times the system just hangs after
| Code: | | Jul 29 11:43:53 ioannidis_host Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled |
in the boot screen.
The thing is that at sometime it boots and everything is working fine. I think that's very weird...
If I boot with the previous kernel I have no problem. Probably I have made some wrong selections in the kernel config but why sometimes it boots and sometimes it doesn't?
Any ideas of what should be the problem?
Thanks! |

hi maestax!
i dont know why your laptop hangs but perhaps you can enable irq sharing for the serial port to solve your problem:
| Quote: |
CONFIG_SERIAL_8250_SHARE_IRQ=y
|
you can find this option through device drivers -> character devices -> serial drivers -> extended 8250/16550 serial driver options -> support for sharing serial interrupts
perhaps this helps you!

Thanks snIP3r!
I will try it and I will post the results.
The thing is that this option wasn't enabled at my previous kernel config but it I was still be able to boot...

ok, make it so.
as far as i can assess this, there were major changes from 2.6.23 to 2.6.25...

Did you run make oldconfig and then follow that up with either menuconfig or xconfig to make sure that you set everything up properly? There have been changes in where certain things are between the .22 and the .25 kernel families. Make oldconfig can only go so far. You still have to make sure things are set properly.
Blessed be!

Hi again,
I set
| Code: | | CONFIG_SERIAL_8250_SHARE_IRQ=y |
but again sometimes the system boots sometimes it doesn't...
Yes, I set up the new kernel with my old config from the .22 kernel. I believe that I will have to go through all options of the kernel once again...
But I still find it weird! One time it boots and one time it doesn't!!!  |

If your system doesn't have serial ports, there is no point in enabling them in the kernel. Be sure you even have them before you say yes.
Blessed be!
