>Number: 4486 >Category: kern >Synopsis: ahc(4) in RELENG_2_2 can't do kernel core dumps >Confidential: no >Severity: non-critical >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Sun Sep 7 09:30:02 PDT 1997 >Last-Modified: >Originator: J Wunsch >Organization: interface business GmbH >Release: FreeBSD 2.2-STABLE i386 >Environment: Any RELENG_2_2 kernel with an ahc(4) driver, and kernel core dumping enabled. Observed for at least half a year now. >Description: When the kernel tries to dump core on the mentioned system, it starts to say `dumping ...', but then jams. The machine needs a hard reset in order to be freed. >How-To-Repeat: Configure a RELENG_2_2 kernel with an ahc(4) driver for kernel core dumping, and cause a panic. Calling `panic' from DDB should suffice. >Fix: Unknown. Suspecting some problem with interrupts enabled, but the driver trying to poll the controller. >Audit-Trail: >Unformatted:
