Hi Alan,
Are there any plans to feedback the bug fixes to Linux 2.6 and 3.2 kernels?
Do Linux developers even feedback bug fixes to older kernels in the first
place?
I use Ubuntu 10.04.4 LTS 32-bit (Canonical support going out in April 2013) and
12.04.1 LTS 32-bit.
I do find quite a few bugs (30+ bugs I have observed with 30+ mainboards I own
myself.) in Ubuntu 10.04.4 and 12.04.1, and before Canonical phases out Ubuntu
10.04.4 LTS, I will like to see as many fixes incorporated into Ubuntu 10.04.4
LTS in particular.
Is there a list of fixes made to USB/ACPI area of Linux that you are
talking about?
I own quite a few NVIDIA, SiS, and VIA Technologies chipset-based mainboards,
and compared to Intel chipset-based mainboards, USB/ACPI S3 State resume is a
lot shakier to say it charitably.
By the way, I always update the mainboard BIOS with the last non-beta version
released by the mainboard manufacturer before filing a bug report.
If the last non-beta BIOS doesn't work for a given mainboard, I will try the
beta version BIOS or go back to one version before the last non-beta version
BIOS. (ASUS often releases beta version BIOS for their mainboards.)
Case in point, I got my ASUS P4S8X-MX mainboard (SiS 661GX/964 chipset) to stop
freezing occasionally when resuming from ACPI S3 State by switching back to
BIOS Revision 0808 rather than the Revision 0901 that used to be on ASUS
website. (Revision 0901 used to be on their website, but somehow disappeared. I
downloaded it 2 or so years ago.)
Although with ASUS P4S8X-MX mainboard, I had to disable its onboard USB within
BIOS setup because of USB/ACPI S3 State resume bug that appeared in Linux 3.2
kernel that didn't exist in Linux 2.6 kernel.
That's the reason why I think bug fixes should go back into the older kernels.
