Been running that kernel since march or so, it has worked flawlessy
through several glibc versions, yes. Downgrading glibc is always such
a mess, though, so I haven't done that yet. :)
Looking at the diff between 2.4.21-rc2 and kernel-source-2.4.21, the
main differences seem to be in the handling of auxio, changing
REGWIN_SZ to STACKFRAME_SZ.
In addition, there seems to be changes in how hardware multiplication
and division is handled (umul/udiv/smul/sdiv). In 2.4.21-rc2,
do_user_muldiv is only called for sun4 and sun4c architectures, while
it is called unconditionally in 2.4.21. Could this be triggered by
some combination of gcc and glibc updates? I'll instrument the 2.4.21
kernel a bit at that point, and start a kernel rebuild before going
home and calling it a day.
