CIA machine check ?



I've found a lot of these in my log:

Apr 25 11:29:12 alf kernel: CIA machine check: vector=0x670 pc=0xfffffc00003350c0 code=0x98
Apr 25 11:29:12 alf kernel: machine check type: processor detected hard error
Apr 25 11:29:12 alf kernel: pc = [clear_page_tables+224/480]  ra = [exit_mmap+452/512]  ps = 0000    Not tainted
Apr 25 11:29:12 alf kernel: v0 = 000000000609c3e0  t0 = 0000000000000001  t1 = 0000000000000004
Apr 25 11:29:12 alf kernel: t2 = fffffc0004dde000  t3 = fffffc0005227de0  t4 = fffffc00005da028
Apr 25 11:29:12 alf kernel: t5 = fffffc00000032b8  t6 = 0000000000000003  t7 = fffffc000609c000

Apr 25 11:29:12 alf kernel: t8 = 0000000004000000  t9 = 0000002170d160d3  t10= 4200000000000000

This lasted about 30 minutes (generating about 800 of these), and for
the past hour it's been quiet.  Any ideas what this can mean? Is it
serious? Hopefully not hardware, my multia died on me last week and this
is my last alpha :-(

It alternates between clear_page_tables+224/480,
clear_page_tables+116/480, clear_page_tables+400/480 and a couple of
others (the others only a few times).

I'm running 2.4.18, on an XLT 366 with 128MB.
