From: "Kenneth D. Merry" <ken@plutotech.com> Subject: quintuple softupdates panic in -stable To: stable@FreeBSD.ORG Date: Mon, 22 Mar 1999 14:51:10 -0700 (MST) Cc: mckusick@mckusick.com, dillon@FreeBSD.ORG I just got this panic on a very heavily loaded -stable server. It is RELENG_3 as of about March 10th. I noticed that Kirk checked in some softupdates bug fixes on March 1st/2nd, but they didn't go into RELENG_3. I'm not sure if this panic would be fixed by those changes. I wasn't able to compile a kernel with debugging symbols that would correspond to the one that was running on the machine in question, so there are no symbols. Sorry. Ken -- Kenneth Merry ken@plutotech.com ... panic: allocdirect_check: old 0 != new 397448 || lbn 12 >= 12 I have never gotten this panic before. The fixes that I put in in early March would probably not have prevented it (though unless I knew what did cause this panic, I can't say that with complete assurance). At any rate, it would be very useful if you could reproducce this panic with a symbolled kernel. For starters, I would like to know the contents of oldadp and newadp (the second and third parameters to allocdirect_merge). It would also be useful to see the elments on the list headed by adphead (the first parameter to allocdirect_merge). The follow-on panics are the usual trash that crops up when trying to sync the filesystem while in the middle of a soft updates panic.
