Please report it in bugzillaPlease report it in bugzillaPosted Jun 12, 2008 6:41 UTC (Thu) by mingo (subscriber, #31122)In reply to: My issues with kernel development by grundler Parent article: Andrew Morton on kernel development (1) isn't really bug since "make oldconfig" is "expected behavior". Try "make menuconfig" and see if a menu driven config tool works better for you. Too often, I find the "Help" text useless and I'm not a kernel newbie. Updating those to be meaningful (e.g. spelling out uncommon acronyms) would help alot of people. It is a serious upstream kernel regression if "make oldconfig" (used on a .config that worked with a previous version of the kernel) suddenly breaks a working setup. Please report it if you get hit by such a bug/regression and it will be fixed. We'd be shooting ourselves in the foot if we made it harder to test new kernels. Ditto for the second bug - if mounting CDs worked well before and it suddenly starts producing spurious "no media" mount failures that's a plain bug/regression. Please report them on bugzilla.kernel.org. Also, if you test new kernels, make sure you run the kerneloops client which automatically reports crashes to kerneloops.org.

Please report it in bugzilla Posted Jun 12, 2008 7:51 UTC (Thu) by pr1268 (subscriber, #24648) [Link] Thank you both for the replies. I'm beginning to wonder if the two issues I have with 2.6.25[.x] are related in a weird way:
Another reason why I was loath to report the CD/DVD not mounting issue was because I have some unusual IDE/SATA hardware in my system (a Promise PDC20271 ATA controller card, a Silicon Image SATA controller card, one of the two DVD burners is IDE whilst the other is SATA), but Linux has ordinarily given me no grief whatsoever for running this odd configuration (I also have a mix of IDE and SATA hard drives and a software RAID-0, but that's another story). Again, I must stress that this could all be a silly case of operator error (I'm good at finding these kinds of bugs ;-) ), or maybe it is a defect that needs the attention of the kernel developers... I will admit that I'm somewhat of an informal kernel tester; I've compiled and run recent (-stable) kernels for the past 3 1/2 years now (thus explaining why I like Slackware--it works well with vanilla kernels), and I've only had to report one show-stopper (Oops in 2.6.15 due to NULL dereference in usbhid.c). Thanks again for your replies; I'll look into reporting the make oldconfig issue.
Please report it in bugzilla Posted Jun 12, 2008 14:25 UTC (Thu) by iabervon (subscriber, #722) [Link] It's possible to have user error with "make oldconfig" on the first try (like getting the wrong config into it), but if you can reproduce it, it's worth reporting. (And if you can't reproduce it, you'll have a correct config...) There was someone recently reporting problems with mounting optical media if he waited more than 30 seconds after inserting it. It might be related, or it might be a coincidence, but you might want to look into http://lkml.org/lkml/2008/6/6/170. The thread is kind of inconclusive, but you might be able to help if you've got a different failure pattern (you need to wait, while other people need to hurry), but also have a problem with timing and optical media insertion that came up between 2.6.24 and 2.6.25. It's got things to try, anyway.
Make oldconfig issue has been reported in Bugzilla Posted Jun 12, 2008 15:23 UTC (Thu) by pr1268 (subscriber, #24648) [Link] I opened a bugzilla bug (#10898) on the make oldconfig issue. Apparently this is a regression reported by Linus himself, and a patch is in the works. Make oldconfig worked fine for 2.6.24.x (as I mentioned in the bugzilla description). As for the mount(8) CD/DVD issue, well, I'll test that later this afternoon... Time to go to work... I'm still not discounting the possibility that a funky config kernel build combined with my strange mix of hardware (see above--yes, that's all one PC!) might have caused this anomaly.
