I'm running davidm's bk kernel, version 2.6.4-rc1, built with gcc-3.3. I've been poking around with SysRq and hit a crash last evening with the following footprint. After this the machine was wedged so badly that the Ethernet MP stopped responding completely, so I was unable to power cycle the machine until I arrived at the office. telnet> send brk SysRq : Show Memory swapper[0]: Oops 8813272891392 [1] Pid: 0, CPU 0, comm: swapper psr : 0000101008026018 ifs : 8000000000000389 ip : [<a00000010005b9e0>] Tainted: GF ip is at show_mem+0x100/0x260 unat: 0000000000000000 pfs : 0000000000000389 rsc : 0000000000000003 rnat: 0000000000000000 bsps: 0000000000000000 pr : 80000000ff556565 ldrs: 0000000000000000 ccv : 0000000000000000 fpsr: 0009804c8a70033f csd : 0000000000000000 ssd : 0000000000000000 b0 : a00000010005b970 b6 : a00000010006dc70 b7 : a0000001002eda00 f6 : 0fffbccccccccc8c00000 f7 : 0ffdaa200000000000000 f8 : 100008000000000000000 f9 : 10002a000000000000000 f10 : 0fffcccccccccc8c00000 f11 : 1003e0000000000000000 r1 : a000000100afd5c0 r2 : ffffffffffffff05 r3 : 000000000103ffef r8 : a0000001009174f0 r9 : a0000001009174f0 r10 : 0000000000000000 r11 : a0000001009172a0 r12 : e0000000047ffb90 r13 : e0000000047f8000 r14 : a000000100848510 r15 : a00000010084dcf8 r16 : a0007fffff0fffb0 r17 : 000000000100ffff r18 : a0007fffff0fffd0 r19 : a0007fffaec00000 r20 : a000000100917508 r21 : 0000000000000000 r22 : 000000000504fffb r23 : 000000000100ffff r24 : 0000000000000000 r25 : 0000000000000001 r26 : 00000000000008eb r27 : 0000000000000001 r28 : a000000100931c12 r29 : 0000000000004b3a r30 : 0000000000000000 r31 : a000000100917258 Call Trace: [<a000000100018420>] show_stack+0x80/0xa0 sp=e0000000047ff760 bsp=e0000000047f96b8 [<a00000010003ca70>] die+0x170/0x200 sp=e0000000047ff930 bsp=e0000000047f9680 [<a00000010005a850>] ia64_do_page_fault+0x350/0x980 sp=e0000000047ff930 bsp=e0000000047f9618 [<a000000100011540>] ia64_leave_kernel+0x0/0x260 sp=e0000000047ff9c0 bsp=e0000000047f9618 [<a00000010005b9e0>] show_mem+0x100/0x260 sp=e0000000047ffb90 bsp=e0000000047f95c8 [<a0000001003928a0>] sysrq_handle_showmem+0x20/0x40 sp=e0000000047ffb90 bsp=e0000000047f95b0 [<a000000100392dd0>] __handle_sysrq_nolock+0x110/0x260 sp=e0000000047ffb90 bsp=e0000000047f9568 [<a000000100392c90>] handle_sysrq+0x70/0xa0 sp=e0000000047ffb90 bsp=e0000000047f9538 [<a00000010040e110>] receive_chars+0x330/0x680 sp=e0000000047ffb90 bsp=e0000000047f9448 [<a00000010040ebf0>] serial8250_interrupt+0x1b0/0x200 sp=e0000000047ffba0 bsp=e0000000047f93d8 [<a000000100014d40>] handle_IRQ_event+0xa0/0x120 sp=e0000000047ffbb0 bsp=e0000000047f9390 [<a000000100015780>] do_IRQ+0x280/0x380 sp=e0000000047ffbb0 bsp=e0000000047f9340 [<a000000100017400>] ia64_handle_irq+0xa0/0x1a0 sp=e0000000047ffbb0 bsp=e0000000047f9308 [<a000000100011540>] ia64_leave_kernel+0x0/0x260 sp=e0000000047ffbb0 bsp=e0000000047f9308 [<a0000001000177c0>] ia64_pal_call_static+0x80/0xa0 sp=e0000000047ffd80 bsp=e0000000047f9000 [<a000000100018e30>] default_idle+0x90/0x140 sp=e0000000047ffd80 bsp=e0000000047f8fd8 [<a000000100019000>] cpu_idle+0x120/0x1e0 sp=e0000000047ffe20 bsp=e0000000047f8f78 [<a000000100008d30>] rest_init+0x90/0xe0 sp=e0000000047ffe20 bsp=e0000000047f8f60 [<a0000001007c4e10>] start_kernel+0x490/0x520 sp=e0000000047ffe20 bsp=e0000000047f8f00 [<a0000001000081a0>] _start+0x280/0x2a0 sp=e0000000047ffe30 bsp=e0000000047f8e90 <<00>>KIenr nienlt eprarnuipct: hAainedel,e rk i-l lniontg siynntceirnrugp h a t -- Aron Griffis hp Linux and Open Source Lab Key fingerprint = 4601 AE87 379D A917 BA62 5263 C284 0366 5E6A 3C6B - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
