Hi All, I am getting something very similar, although on a different line in slab.c Linux version 2.4.29-uc0 (xilinx@debian) (gcc version 2.95.3-4 Xilinx EDK 6.3 Build EDK_Gmm.11.2) #4 Mon Mar 14 12:42:18 GMT 2005 On node 0 totalpages: 8192 zone(0): 8192 pages. zone(1): 0 pages. zone(2): 0 pages. CPU: MICROBLAZE Console: xmbserial on UARTLite Kernel command line: ° Calibrating delay loop... 3.68 BogoMIPS Memory: 32MB = 32MB total Memory: 30260KB available (1178K code, 968K data, 44K init) kernel BUG at slab.c:682! This is on a new board build (the memory is known good), and this is not a known good toolchain (my first try on this linux box). CVS dist and kernel was downloaded from scratch on Sunday. MHS, MSS and config.in included, incase it helps!

The compiler should promote the 0 to 0L automagically. What was the bogus value passed to the lwoer level function? > What's curious is this: the fix doesn't appear in the current CVS archive. > So, my question is, how is anyone running successfully with this bug > present? That code is stable and works across all nommu arches, microblaze included. I'm more inclined to suspect something specific to your setup. When did you last update your kernel sources (not that it should matter in this instance)? What compiler version are you using? Also, can you run mb-objdump -S over the slab.o file, and see what sort of assembly is being generated?
