It's spinlock for 2.2 and 2.4 kernels, and save_flags for 2.0.
Tim, did you cc Gerard Roudier? He mainains the sym53c8xx driver. All

calling schedule() causes a panic() in schedule(), and even an innocent

from an softirq causes runqueue corruptions.[you must use

Could you post the output of
#tulip-diag -mm -aa -f
with the broken driver?
Some code that's required for Linksys Tulip clones was moved from pnic
specific part into the generic part, perhaps that causes problems.

I have 2 ideas:
* glibc corrupted
* did you downgrade the cpu?
RH 7.0 automatically installs glibc for a Pentium Pro or later if that
cpu is present during install.
If you then move the hd into a computer with an AMD K6, it won't boot.
I'd run
