Bug ID: 203839
Summary: Kernel 5.2-rc3 fails to boot on a PowerMac G4 3,6:
systemd[1]: Failed to bump fs.file-max, ignoring:
invalid argument
Product: Platform Specific/Hardware
Version: 2.5
Kernel Version: 5.2-rc3
Hardware: PPC-32
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: PPC-32
Assignee: [email protected]
Reporter: [email protected]
Regression: No

Created attachment 283135

failed boot, screenshot 5.2-rc3

The system boots fine with kernel 5.1.7. Starting with 5.2-rc1 the G4 got problems to correctly finish booting. With 5.2-rc3 basic boot process seems to complete, but crashes when handing control over to systemd:

systemd[1]: Failed to bump fs.file-max, ignoring: invalid argument systemd[1]: segfault (11) at 0 nip 0 ir 0 code 1 systemd[1]: Bad NIP, not dumping instructions
[...]

For more details see the screenshot. Kernel 5.2-rc1 errors out even earlier (see screenshot) with a different error. Also this problem maybe is 32bit specific. Tried 5.2-rc3 on a PowerMac G5 which boots successfully without problems.

root is ext4, boot is ext2, systemd is v241.

--- Comment #5 from Christophe Leroy ([email protected]) --- Then the problem is not due to the rework of syscalls.

Are you able to bisect ?

bisect took me a while due to quite some skips. Cherry-picking 397d2300b08cdee052053e362018cdb6dd65eea2 and 305d60012304684bd59ea1f67703e51662e4906a helped me complete it.

powerpc/32s: set up an early static hash table for KASAN.

KASAN requires early activation of hash table, before memblock() functions are available.

This patch implements an early hash_table statically defined in __initdata.

During early boot, a single page table is used.

For hash32, when doing the final init, one page table is allocated for each PGD entry because of the _PAGE_HASHPTE flag which can't be common to several virt pages. This is done after memblock get available but before switching to the final hash table, otherwise there are issues with TLB flushing due to the shared entries.

CONFIG_SMP must (again) be the reason we missed it.

Can you please try the change below ?

Applied your change on top of 5.2-rc4. The G4 boots fine again, thanks!
