Re: crashes on 4.5-RELEASE
I have a fbsd file server that doesn't crash. The box that crashes is nfs mounting /usr/ports from the server. My thoughts are that there is some interaction in the nfs code with the xl driver. -jan- -- Jan L.

Ahh yes, everything in this area used to work fine (including 'shutdown -p'), but broke after Warner made the PCI-routing changes for PCCARD. He can reproduce it with his hardware, and it's not a real big thing anyway (plus he's doing some good work *waves*, don't wanna distract him with trifles).. Just 'halt' the machine, and use the little power key in the top-left corner when it says to "Press Any Key". It'll startup clean. Cheers, AS msg41843/pgp0.pgp Description: PGP signature
crashes on 4.5-RELEASE
Okay, I'm pretty sure this isn't a hardware problem now. I was seeing periodic crashes with 4.5-RELEASE on a new laptop I was building. Various posts on this list convinced me that I had a hardware problem. I tried swapping out the RAM and it seemed to crash less (and in a different place). Crashes after swapping the RAM were always in the xl routines. So, being convinced that I had a hardware problem (mother board or cpu or something like that), I swapped out the *entire machine*. I'm still seeing the crashes. So, I have /usr/ports nfs mounted from another freebsd box. I cd /usr/ports/misc/instant-workstation; make install The machine panics (sometimes right away, sometimes after several minutes). Here's the panic message: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xc0fcec39 fault code = supervisor write, page not present instruction pointer = 0x8:0xc0205243 stack pointer = 0x10:0xcde4fbd0 frame pointer = 0x10:0xcde4fbe4 code segment= base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags= interrupt enabled, resume, IOPL = 0 current process = 80 (nfsiod) interrupt mask = net tty kernel: type 12 trap, code=0 Stopped at nfs_realign+0xdb: incb0(%eax,%edx,1) db> trace nfs_realign(c0ea5200,14,0,1,cdeb0cc0) at nfs_realign+0xdb nfs_receive(c17ca280,cde4fc6c,cde4fc70,0,1) at nfs_receive+0x45d nfs_reply(c17ca280,cde4fdc0,0,20,10) at nfs_reply+0x45 nfs_request(ce0b3c80,c0e5bf00,6,0,c16dcc80) at nfs_request+0x39a nfs_readrpc(ce0b3c80,cde4fdc0,c16dcc80,c68a25b8,cdeb0cc0) at nfs_readrpc+0x538 nfs_doio(c68a25b8,c16dcc80,0) at nfs_doio+0x14b nfssvc_iod(cc379740,cc379740,2,cde4ff80,c37d880) at nfssvc_iod+0x1c2 nfssvc(cc379740,cde4ff80,2,0,bfbffdd8) at nfssvc+0x6f syscall2(2f,2f,2f,bfbffdd8,0) at syscall2+0x1f5 Xint0x80_syscall() at Xint0x80_syscall+0x25 db> FYI, this machine is an HP Omnibook 6000.

Re: crashes on 4.5-RELEASE
Just another datapoint... I turned off softupdates. The machine crashed in the xl code.

Re: crashes on 4.5-RELEASE
Looks like I'm not the only one seeing this: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/22494 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/31710 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/30952 I suspect these are all the same problem. -jan- -- Jan L.
