CIP testing did not find any problems here:

https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/tree/linux-6.1.y

Tested-by: Pavel Machek (CIP) <pavel@denx.de>

It would be good to quote sha1 of the release, so that we could check
it against our build system.

Best regards,

Hello,

Kernel hangs during early boot. No console messages, nothing in pstore.

Tested on a HP 17-by0001nw laptop with an Intel Kaby Lake CPU (Intel i3-7020U) and Ubuntu 20.04.

This CPU is not affected by RFDS (at least according to the Kconfig message), so I have set

CONFIG_MITIGATION_RFDS=n

in Kconfig. I do not have any updated microcode (if any will be provided at all for this CPU).

Greetings,

Mateusz

I have tested with the following patches reverted:

                [PATCH 6.1 43/71] x86/mmio: Disable KVM mitigation when X86_FEATURE_CLEAR_CPU_BUF is set
                [PATCH 6.1 44/71] Documentation/hw-vuln: Add documentation for RFDS
                [PATCH 6.1 45/71] x86/rfds: Mitigate Register File Data Sampling (RFDS)
                [PATCH 6.1 46/71] KVM/x86: Export RFDS_NO and RFDS_CLEAR to guests

and the kernel still doesn't boot.

I have realized that in Kconfig, I have CONFIG_DEBUG_PREEMPT enabled for some weird reason.
I alsa have CONFIG_EARLY_PRINTK_USB_XDBC=y, which may cause error messages not to
appear on screen (according to Kconfig description). Will test with both options disabled.

Greetings,

Mateusz

If the bisected commit is in there, then yes we need it. It's marked as
fixes that, so puzzled why it isn't in there?

Sorry, I take it back - both e33b93650fc5 ("blk-iocost: Pass gendisk to
ioc_refresh_params") and d3d517a95e83 ("blk-rq-qos: make rq_qos_add and
rq_qos_del more useful") are currently in the 6.1 tree.

I'll go ahead and drop the backport of f814bdda774c ("blk-wbt: Fix
detection of dirty-throttled tasks") as well as the dependencies (which
is where this issue bisected to), and all follow-up fixes.

We can revisit this for the next release.
