FWIW, that is 449d0d84bcd824 ("firmware: qcom: scm: smc: switch to using
the SCM allocator") [v6.11-rc1] which was authored by Bartosz
Golaszewski and commited by Bjorn Andersson.

Better include the exact problem you face in your report so
that search engines can do their magic; makes it also easier
to handle for everyone.
Furthermore two quick questions:
[ 0.000000] Linux version 6.10.0-rc1-msm8960+ (a@fpx-l-AMER03105) (Ubuntu clang version 16.0.6 (15), Ubuntu LLD 16.0.6) #17 SMP Sat
Is that a vanilla kernel or one close to it? That "msm8960+" sounds
somewhat suspicious.
And does the problem still happen with latest mainline? Cconsider
retrying with -rc5, which should be out in the next 24h.
And FWIW, here is the afaics relevant part of the problem:
