I believe I've narrowed down the cause of my oopses/panics:
If I build with CONFIG_MK7 but comment out
define_bool CONFIG_X86_USE_3DNOW y
in the MK7 part of arch/i386/config.in, the 2.4.4 kernel appears to run perfectly.
On a side note, if I leave arch/i386/config.h untouched but force the use of the generic MMX implementations of fast_clear_page() and fast_copy_page() in arch/i386/lib/mmx.c, then I get some odd behavior but nothing as bad as I had been getting before. (For example, running awk always produces the message "awk: cmd. line: 1: (FILENAME- FNR=1) fatal: attempt to access field -2147483648".)
Could this be a sign of a faulty 3DNOW! core in my CPU? If so, do you know of any utilities I could run that test these instructions? (For Linux or Windows.)
The CPU is a 1.2GHz Athlon Thunderbird with a 266MHz frontside bus. In case it's helpful, I've attached the contents of /proc/cpuinfo.
Thanks in advance to anyone who can help!
