679 Some other things you should try when experiencing seemingly random,
680 "weird" problems:
681
682 1) make sure that you have enough swap space and that it is
683 enabled.
684 2) pass the "no-hlt" option to the kernel
685 3) switch on floating point emulation in the kernel and pass
686 the "no387" option to the kernel
687 4) pass the "floppy=nodma" option to the kernel
688 5) pass the "mem=4M" option to the kernel (thereby disabling
689 all but the first 4 MB of RAM)
690 6) make sure that the CPU is not over clocked.
691 7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
692 8) disable the cache from your BIOS settings
693 9) install a fan for the video card or exchange video RAM
694 10) install a better fan for the CPU
695 11) exchange RAM chips
696 12) exchange the motherboard.

6 /* These are here in an effort to more fully work around
7 * Spitfire Errata #51. Essentially, if a memory barrier
8 * occurs soon after a mispredicted branch, the chip can stop
9 * executing instructions until a trap occurs. Therefore, if
10 * interrupts are disabled, the chip can hang forever.
11 *
12 * It used to be believed that the memory barrier had to be
13 * right in the delay slot, but a case has been traced
14 * recently wherein the memory barrier was one instruction
15 * after the branch delay slot and the chip still hung. The
16 * offending sequence was the following in sym_wakeup_done()
17 * of the sym53c8xx_2 driver:
18 *
19 * call sym_ccb_from_dsa, 0
20 * movge %icc, 0, %l0
21 * brz,pn %o0, .LL1303
22 * mov %o0, %l2
23 * membar #LoadLoad
24 *
25 * The branch has to be mispredicted for the bug to occur.
26 * Therefore, we put the memory barrier explicitly into a
27 * "branch always, predicted taken" delay slot to avoid the
28 * problem case.
