What I had observed with an old Athlon were some random lockups. I was
trying to setup a samba print server at the time, and the lockup always
occured when some windows machine was trying to use the shared printer
through network. I think the IO-APIC was also enabled. Then, at some
later time, I read somewhere on the internet that the IO-APIC or LAPIC
could be buggy on some Athlons, so I understood what had happened to
me. So, I did not investigate this issue any further.
I didn't either, especially because it works with lapic disabled in the
kernel config. I just thought that this oops might be useful to somebody.
