Hello,
while boot process, partition size of sda6 is detected with wrong size with archlinux32-iso-installer 20221102:
root@archiso ~ # fdisk -l /dev/sda
Disk /dev/sda: 27.95 GiB, 30005821440 bytes, 58605120 sectors
Disk model: IC25N030ATMR04-0
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x8d5ae552
Device Boot Start End Sectors Size Id Type
/dev/sda1 2048 16136191 16134144 7.7G c W95 FAT32 (LBA)
/dev/sda4 16136192 58605119 42468928 20.3G 5 Extended
/dev/sda5 16138240 17186815 1048576 512M 83 Linux
/dev/sda6 17188864 58605119 41416256 19.7G 83 Linux
root@archiso ~ # blockdev --getsz /dev/sda6
35215157
root@archiso ~ # partprobe
root@archiso ~ # blockdev --getsz /dev/sda6
41416256partprobe "fixes" the issue temporarily.
With archlinux-iso-installer 20161201 (32 bit) this failure doesn't exist after booting.
Normally, sda6 has an LV, which itself has archlinux-root-filesystem inside. It was removed for debugging/finding the problem.
Because of the size mismatch LV won't become active on boot, archlinux-root-filesystem is missing and archlinux-system is not able to boot.
pvscan outputs following error message:
WARNING: Device /dev/sda6 has size of 35215157 sectors which is
smaller than corresponding PV size of 41416256 sectors. Was device resized?Similar to here.
Problem started, when moving archlinux-root-filesystem from physical disc-partition into lvm months ago. So I cannot say at the moment, which kernel version / linux-image problem started.
Usage of this machine was paused in hope, problem in kernel/tools/utils will be fixed, but doesn't seem so.
Hardware is IBM Thinkpad R40e, Product Name: 2684QRG, BIOS-Version: 1SET70WW (1.38 )
Thanks for help and tipps,
Stefan
Update 1: Latest tested iso without problem is this one.
Tested first problematic iso is this one.
In between the kernel and initrd was renamed, maybe it's a hint to find the problem:
vmlinuz -> vmlinuz-linux
archiso.img -> initramfs-linux.img

Personally I doubt the renaming of the kernel files has caused this, that seems more like a bit of fluff that is a built artefact of some makefile or other. I note blockdev is owned by util-linux, so we need to look at what version that was at when it last worked, but unfortunately just now I'm at a loss to where the old packages are kept, I thought it used to be linked from the homepage here, but it seems that is no more. Presumably that misidentification of the size of that logical volume stops the fs being mounted fully and so stops the machine booting fully. Perhaps that issue hasn't affected me because I don't use logical volumes, and I don't run any OS other than archlniux on my boxes, so 4 partitions is enough for me.
Architecture: pentium4, Testing repos: Yes, Hardware: EeePC 901+2GB RAM+OS half on the SD card.

Update2:
Archlinux32 with LV running booted with downgraded linux-lts-kernel 5.4.98-1.0-lts and lz4-compression activated in /etc/mkinitcpio.conf.
dmesg shows unfunny "size/sectors mismatch"-, "capacity change" and "HPA detected" messages while booting, so maybe it's a timing issue on newer versions of kernel:
dmesg-grep for 'ata1\|sda' of four boots:
1+2: OK with iso-archliveimages 20161201 and 20201101
3th: OK with linux-lts-kernel 5.4.98
4th: KO with linux-kernel 5.17.5-arch1-1.2 with additional message "5.924421] sda: p6 size 41416256 extends beyond EOD, truncated" compared to the three OK boots.
5th: KO with iso-archliveimage 20210225 with additional message "5.924421] sda: p6 size 41416256 extends beyond EOD, truncated" compared to the three OK boots.

An ugly workaround could be, to only use disk to sector 52404020 instead of 58605119, maybe i will test it some day, but nicer would be fixing the initial cause of the problem.

As far as I read HPA is a "feature" to protect your hard disk somehow.. thusly shrinking it during boot.
Maybe you can disable this feature in the BIOS?
https://forums.unraid.net/topic/10229-h … ent-sizes/
If that's fatal to the data on the drive I cannot really tell..but it shouldn't IMHO.
If it is a kernel thing, then maybe some of this special code handling HPA is not up to date or so..

There is only a feature called "IBM Predesktop Area" in Security-Tab of the BIOS: "Holds recovery image(s), HW diags, service utils.
* Normal: Change allowed; contents hidden from OS.
* Secure: No user or SW-initiated changes.
* Disabled: Not Usable. Visible and reclaimable."
Changed from "Normal" to "Disabled" (with popup message cited below), but strangely, it didn't change anything regarding the above problem:
Problem exists with linux-lts-5.15.90-1.0 and archlinux32-installer 2021.02.25.
Popup message:
"Attention! If you select Disabled, the IBM Predesktop Area will be visible and can be reclaimed by the OS. Once the area is overridden by OS tools, it can't be used with Normal or Secure again and you will need to opbtain a Recovery CD to retrieve original HDD."
If it is a kernel thing, then maybe some of this special code handling HPA is not up to date or so..
Obviously there must have taken place a code change in kernels after linux-lts-5.4.98-1.0.
All in all, meanwhile it is rather complex to maintain and keep booting this machine (IBM Thinkpad R40e)., e.g. at the moment it needs following boot parameters to boot without failure
"noapic pci=assign-busses apicmaintimer idle=poll reboot=cold,hard"
and max. kernel version linux-lts-5.4.98-1.0.
