Aucbvax.2206 fa.unix-wizards utzoo!duke!decvax!ucbvax!greg@NPRDC Fri Jul 10 11:18:07 1981 Has anybody seen this problem before? From: greg at NPRDC I am having a problem, the symptoms of which are as follows: a kernel buffer is acquired (via NODEV) and a data structure built in it. The structure is immediately used (within the same system call), and it is OK. Sometime later, an attempt to use the data structure bombs, and a dump of the buffer shows that it apparently contains a disk record. The buffer is still correctly assigned to NODEV; just the data has been changed. It acts as if the buffer was assigned (maybe to a read-ahead block?), and then freed (and reassigned to NODEV) before the I/O had completed. Has anybody seen this before? Is there a cure? ----
