Not sure whether this is still of relevance; I've noticed the "soft lockup detected" message on my Toshiba Tecra A8 a couple of times this morning, leaving the machine unable to boot at all. It's a completely new install, first time Linux installation on that very machine, so I can't say whether or not it used to be different before. However, two things:

- The notebook also is equipped with an ipw3945 based NIC, but obviously whether or not the "kill switch" is enabled doesn't matter much - at least the "BUG:" message appeared both having WLAN enabled and disabled, and the machine also managed to boot up cleanly most of the time both having WLAN dis- or enabled.

- Not sure whether this is anyhow related to that issue, I see my kernel log being flooded with messages like this

[17184770.548000] APIC error on CPU0: 40(40)
[17184770.548000] APIC error on CPU1: 40(40)

Kernel is Edgy 2.6.17-10-generic.

Cheers,
