Ok, I can reproduce this on a kernel from today: acd0: CDRW at ata3-master PIO4 Mounting root from ufs:/dev/ad0a IOMMU fault virtual address 0xc0620000 panic: pcib: uncorrectable DMA error AFAR 0x3f867880 AFSR 0x270000ff00000000 cpuid = 0; KDB: enter: panic [thread 100042] Stopped at kdb_enter+0x38: ta %xcc, 1 db> tr panic() at panic+0x1a8 psycho_ue() at psycho_ue+0x60 intr_fast() at intr_fast+0x88 -- interrupt level=0xd pil=0 %o7=0xc02b474c -- spitfire_block_zero() at spitfire_block_zero+0x74 vm_pagezero() at vm_pagezero+0x1b8 fork_exit() at fork_exit+0x9c fork_trampoline() at fork_trampoline+0x8 db> And a kernel from the 10th does not appear to have the problem. I'll do a little playing with CVS to see if I can locate exactly what commit does it. -- Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel |
