Hello. Today, I got the following panic: Fatal trap 12: page fault while in kernel mode cpuid = 7; apic id = 07 fault virtual address = 0x188 fault code = supervisor read, page not present instruction pointer = 0x8:0xffffffff80255ea7 stack pointer = 0x10:0xffffffffc1832500 frame pointer = 0x10:0x0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = resume, IOPL = 0 current process = 608 (ls) trap number = 12 panic: page fault cpuid = 7 It happened, when I had... dd if=/dev/da1 of=bzzz count=10 bs=1073741824 ... running on the first console and tried 'ls bzzz' on the other. [...] isp0: <Qlogic ISP 2312 PCI FC-AL Adapter> port 0x3000-0x30ff mem 0xe7002000-0xe7002fff irq 37 at device 1.0 on pci37 [...] da1 at isp0 bus 0 target 0 lun 0 da1: <SB-3160F S > Fixed Direct Access SCSI-2 device da1: 200.000MB/s transfers, Tagged Queueing Enabled da1: 841784MB (1723973632 512 byte sectors: 255H 63S/T 107312C) [...] [1] Before that, when trying to read a few small blocks from the same device, we got pretty strange output -- looking like a looped first block "count" times. I guess I will have to try to get vmcore to have any chance to interest someone with it. And that won't be easy as the box has 16GB of RAM and, unfortunately, the FC array we used, is normally connected to the production box and we can't really experiment on it freely. [1] dmesg (non-verbose; verbose one is far too verbose, thanks to mpt; and without the mentioned before da1, as we had to reconnect the array to the proper machine) attached. -- Krzysztof Kowalik | () ASCII Ribbon Campaign Computer Center, AGH UST | /\ Support plain text e-mail
