Here's another crash that hopefully shows more relation to the cardbus card, so I changed the subject again... I could not get a dump for this because the disk was not responding, (I guess that was because interrupts were masked?) so this is copied from a piece of paper, and the trace has some omissions (still no serial on this thing). uvm_fault(0xd080eb20, 0x1200f00, 0, 1) -> e fatal page fault (6) in supervisor mode trap type 6 code 0 eip d03cdda2 cs 50 eflags 10297 cr2 1200ffff cpl 60 panic: trap type 6, code=0, pc=d03cdda2 --- trap (number 6) --- ieee80211_tree_RB_MINMAX(d1d64030, 1200ffff, dc251d40, 0) at ieee80211_tree_RB_MINMAX+0x5a ieee82011_find_rxnode(d1d64030, 1200ffff, 0, 800, 0) at ieee82011_find_rxnode+0x1a rt2560_decryption_intr(d1d64000, dc278000, 20, ffffffff) at rt2560_decryption_intr+0x197 rt2560_intr(d1d64000, 4, 0, 1) at rt2560_intr+0x71 pccbintr_function(d1bdf600) at pccbintr_function+0x71 Xintr_ioapic2() at Xintr_ioapic2+0x74 The network the card was connected to is using WEP.
