It's a highmem scanning problem, these were supposed to be fixed in a series of changes back in 2.4.8-pre, but they're not completely gone yet. I've cc'd a few people who've shown interest in this ugly^H^H^H^H particular corner of the kernel, but now I'm shutting down for the night. Guys, can you please take a look at this one? It's time to put the highmem allocation problem definitively to rest. Most likely, this problem occurs in -ac as well, just with less frequency. > Daniel Phillips writes: > > On August 21, 2001 06:48 pm, Sven Heinicke wrote: > > > Yes, highmem was on, the stystem got 4G of memory.
