I believe that I *have* seen this happen to me. I'm using a Compaq R3000 laptop with AMD-64 CPU and Gentoo with kernel 2.6.24-rc6-mm1. A few days ago I crashed it twice in a row by trying to load my Comics bookmarks as tabs (87 entries) in 32-bit Firefox. I only got 1 and 3/4ths lines output by netconsole and it mentioned a function with 32-something in the name. Later tonight I can try loading the tabs in Firefox again to see if it will reproduce for a 3rd time. I also have to say that the NMI watchdog, supposedly Non-Maskable, hardly *ever* works for me. I don't believe that whatever events reset the dog actually matter to the end user. Perhaps its still processing interrupts and running a timer loop but if nothing can read or write disk, net, netlink or other device IO, I don't believe the system can actually claim to be working. --=20 Zan Lynx --=-Tj6UwCiZx8KvkHKIUBCu Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.8 (GNU/Linux) iEYEABECAAYFAkeGq7IACgkQG8fHaOLTWwh0hwCfYoXlzQ410jT03L4YcCLUZ5N3 6ugAn2u/kywBwtNifJmb0Ywlr/9P4A39 =FUuf -----END PGP SIGNATURE----- --=-Tj6UwCiZx8KvkHKIUBCu-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
