I compiled the nicstar ATM nic driver. The following happens : swapper(1): Kernel Bug 1 pc = [<fffffc0000341df0>] ra = [<fffffc00003c2154>] ps = 0000 v0 = 0000000000000000 t0 = 0000000000000000 t1 = fffffc0000513c60 t2 = 0000000000000000 t3 = 0000000000000000 t4 = fffffc87002b00c8 t5 = 0000000000000000 t6 = 0000000000000000 t7 = fffffc0001cd4000 a0 = 0000000000000000 a1 = 0000000000000000 a2 = fffffc0001cd4000 a3 = fffffc0001cd7cc0 a4 = 0000000000000000 a5 = 0000000000000000 t8 = 0000000000000000 t9 = fffffc0000412448 t10= 0000000000000007 t11= 000000000000000a pv = fffffc0000341ce0 at = 0000000000000000 gp = fffffc0000534ec8 sp = fffffc0001cd7d90 Code: 47ff0400 or zero,zero,v0 c3e00006 br .+28 40431402 addq t1,24,t1 a4220000 ldq t0,0(t1) f43fffcd bge t0,.-200 00000081 call_pal 129 *47ff0400 or zero,zero,v0 2fe00000 ldq_u zero,0(v0) Trace:3c2154 372f68 310000 310080 310080 310098 310630 310080 310604 3105d8 310604 Kernel panic: Attempted to kill init! I see there are a lot of unsigned long in the driver and I suspect this may be the cause. Can someone tell me what happens ? Oh, right, it's a ev56a on a ruffian board, exact kernel is : 2.4.0-ac6 I hope I typed the oops message correctly, since no drive was mounted as it happened.
