| |
ok, after the Nth time of shipping my laptop back to depot, i've gotten a motherboard back that seems to spaz with IDE DMA.
when i compile IDE DMA into my kernel, it starts booting then locks up when checking the first partition of hda. it prints '..lost interrupt' then it locks up hard. i have to power cycle to get it back.
this is very VERY similar to the problem i had before i shipped it to depot (btw, i shipped it because it overheated from being on the carpet :() which was i would get the above, i.e. lost interrupt and hard lockup, about five seconds after resuming from suspend.
today i have tried 2.2.12, 2.2.13, 2.2.14, 2.3.22, 24, 26, 27, 29, 32, and 33.
currently i'm running IDE w/out DMA, PIIX4: (trimmed dmesg) Linux version 2.3.33 (root@Huntington-Beach) (gcc version pgcc-2.95.1 19990816 (release)) #11 Thu Dec 16 15:18:52 PST 1999 Detected 366364598 Hz processor.

(side note, someone want to put get_random_bytes() earlier?)

right up there is where it would explode. it's an AMI BIOS, if someone has tools to grab more info or wants to peek into the machine, hollar at me.
ideas? comments? flames for the burgers?
