32-bit hardware support

Postby jdmcc » 2018-11-14 09:37

Hi,

Can anybody tell me if there is a planned end of support for Debian on 32-bit hardware?

Nothing has been announced and I doubt it will be too for some time. But sadly, 32 bit support will die at some point.

Thanks for that. Sure, it's bound to go sometime, I just wondered if the Debian developers had a date in mind. I read somewhere on the Linux Mint forum that 32 bit would likely to be supported until 2023, then noticed that kernel 4.9 was also supported until then, and wondered if the two were connected. Anyway, I expect my Dell Optiplex 755 to have given up the ghost by then.

Dell Optiplex 755 is a 64 bit computer.

:oops:
You are absolutely right! I have just successfully installed Ubuntu 16.04 x64 (it was the onlyx64 media I had around) on the Dell and it all seems fine.
I picked up this box second-hand about 7 years ago with 32-bit Windows XP on board, and just went with the updates through Windows 7 to Windows 10, all the time assuming it was 32-bit hardware. Now, when I desperately want to drop Windows for Linux, I've been focusing on those that still support 32-bit. What an ass!

Thanks Segfault, time to look at some more distros.

Don't be ashamed. IT guys at my work didn't know Core 2 Duo is a 64 bit CPU. They were so obsessed with 32 bit Windows.

I'm pretty sure that "lscpu" in the terminal will clear up any confusion about your CPU's capabilities.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Flightgear 2018.2.2, 4.19.5 kernel, wine-staging 4.0~rc1, Pale Moon 28.2.2, Mesa 18.2.6, Midori 7.0

I recently tried to run debian-live-9.6.0-amd64-xfce (1) and devuan_ascii_2.0.0_amd64_desktop-live (2) (*.iso hash checked) on a pc with:

Intel Core 2 Duo Processor E4300

and both hanged during launch:

(1) Kernel panic - not syncing: fatal exception in interupt
(2) Fixing recursive fault but reboot is needed

32-bit versions ran smoothly though.

Debian stock kernel didn't like it. Does not mean it cannot run 64 bit. I ran 64 bit Gentoo on similar CPU for longest time.
