b) Even after applying the patch also it is giving same softlockup issue as
mentioned above:

Hi Anushree,

There was a v2 of this patch sent here:

   https://lore.kernel.org/all/20260812034628.1122115-1-vaibhav@linux.ibm.com/ (local)

Did you get a chance to test it? Could you verify if the issue persists
with the v2 as well?

Thanks,
Amit

Though I have enough vcpus and memory on the guest (16 vcpus , 13Gi of
memory)  and ample amount of memory and cpus
present on host still these softlockups are happening after applying the
patch too. I tried reducing stress also on the guest
but still this issue is seen.

stress-ng --cpu 4 --vm 2 --vm-bytes 1G --hdd 2 --hdd-bytes 1G --sched other
--timeout 3600000s

If you are planning to send next version of this patch,
Please do add my reported-by:

Hi Amit,
Yes I have tested this patch too and I am still seeing the issue. Let me
reply back for this v2 patch also.

Thank you,
