Here's a stack trace: ======================================================================== tulip_txput (sc=0xf08b5800, m=0xf0538f00) at machine/pmap.h:172 (kgdb) where #0 tulip_txput (sc=0xf08b5800, m=0xf0538f00) at machine/pmap.h:172 #1 0xf01cb4ad in tulip_ifstart_one (ifp=0xf08b5818) at ../../pci/if_de.c:4843 #2 0xf017965c in ether_output (ifp=0xf08b5818, m0=0xf0536000, dst=0xf336cb70, rt0=0xf08e7f00) at ../../net/if_ethersubr.c:385 #3 0xf018b6f8 in ip_output (m0=0xf0536000, opt=0x0, ro=0xf336cb6c, flags=0, imo=0x0) at ../../netinet/ip_output.c:532 #4 0xf018ff11 in tcp_output (tp=0xf336cba0) at ../../netinet/tcp_output.c:695 #5 0xf0190f4f in tcp_timers (tp=0xf336cba0, timer=0) at ../../netinet/tcp_timer.c:295 #6 0xf0190d64 in tcp_slowtimo () at ../../netinet/tcp_timer.c:151 #7 0xf014bdc3 in pfslowtimo (arg=0x0) at ../../kern/uipc_domain.c:235 #8 0xf013bb63 in softclock () at ../../kern/kern_timeout.c:124 ======================================================================== And here's the snippet of code in question from pmap.h: static __inline vm_offset_t pmap_kextract(vm_offset_t va) { vm_offset_t pa; if ((pa = (vm_offset_t) PTD[va >> PDRSHIFT]) & PG_PS) { pa = (pa & ~(NBPDR - 1)) | (va & (NBPDR - 1)); } else { pa = *(vm_offset_t *)vtopte(va); pa = (pa & PG_FRAME) | (va & PAGE_MASK); } return pa; } The kernel is a CAM kernel based on source from Saturday. (July 11th) This is *not* a CAM problem, however, since I can reproduce the behavior that leads to the panic on a stock current kernel. I think it's dying in vtopte(). The way I reproduce this is: machine A: P6/233, 128MB RAM, Adaptec 2940, Intel 82558 machine B: P5/133, 32MB RAM, Adaptec 2940, DEC 21140-based card both machines are running -current + CAM as of Saturday - rlogin from machine A to machine B - do a find . -print on machine B - find process hangs almost immediately, in the 'ttywri' state. - I can still do things on the console, and I can still do network I/O to and from the box even. - if I do one more keystroke in the rlogin session (xterm), machine B locks up hard. Numlock doesn't work, ctl-alt-esc doesn't work, ctl-alt-del doesn't work. - I waited a while, and then got the above panic I can reproduce this at will on machine B. I've attached the kernel config file and dmesg output. I previously had a kernel based on sources from July 6th on the machine. That kernel worked just fine. I know that Peter Wemm made a small change to the DEC driver on July 8th, but I'm not positive that it's the source of the problem. I have tried disabling, the ipfw code and the snp device, with the idea that they might be contributing to the problem. That made no difference. The next step is to put an Intel card in and see if I get the same behavior with the fxp driver. I'm trying to track down a spare card now... Anyway, if anyone has seen similar behavior, let me know.
