When I run my machine with a current kernel I get the following message to my terminal, repeated ad nausium: PANIC: INIT: segmentation violation at 0x804a08c (code)! sleeping for 30 seconds! I've been working off of Linus' BK repository and was finally able to get a "working" kernel when I backed up to approximately 2002-12-30 (which is sometime between 2.5.53 and 2.5.54). That kernel works just fine. Sometime between December 30 and January 1 a patch was added that causes the kernel to go into an infinite loop of Oopses. Then sometime later the behavior changed to the INIT problem I mentioned above. Does anyone have any clue how to deal with this? I can assure you that it is NOT a hardware problem (otherwise why would the same hardware work with 2.4 and 2.5.53+?) The only change being made here is the kernel. I have not had a chance to back out each and every ChangeSet individually between Jan1 and Dec30 to figure out what was causing the stream of oopses -- nor am I even confident that that would lead me to a solution for the "PANIC: INIT" problem. In case anyone cares, the most recent ChangeSet from my confirmed-working (2.5.53+) tree is labeled: 1.1004 02/12/30 13:47:09 torvalds@home.transmeta.com +2 -0 Make x86 platform choice strings more easily selectable However I have not guaranteed that this is the Changeset just before it failed (I'm not enough of a bk guru to figure out how to pull down one changeset at a time). Any advice would be greatly appreciated.... I'd be more than happy to try things out for people if you have tests you want me to run.
