Ah...that's why I switched back to my native dsdt. Maybe Bruno has a
2-battery machine! ;)

I have never seen the interrupts more evenly distributed (my interrupt
distribution is identical to yours). But I would like them to be!
Having all this stuff share interrupts causes no end of problems.

I am not using a patched dsdt...I tried the tosh3k patched dsdt and it
improved nothing but messed up the battery, as you observed above.

So mine has stopped turning itself off (I don't know how or why it
stopped turning off). Now it hangs and continues to run. (I sent an
earlier report about this, but nobody seems to be paying attention to us
;) I left it running for a while and noticed that after I moved the
mouse the screen unblanked after like 1/2 hour. It's still processing,
just one clock tick per minute or something... Also the clock was
horribly off after reboot.

I have still never seen the temperature swings you mention.
