I've been getting this panic when I've installed new kernels the last
couple of times. The panic is occuring when I have freshly booted the
system with a new kernel and logged on for the first time. It appears
to occur at the point at which I start fetchmail in my profile, FWIW.
BTW: My home directory is mounted over nfsv3,udp from a Solaris2.6
server with amd. I've tried getting rid of amd and it makes no
difference.
At the moment, I'm having to use a kernel from June 8th, to be able to
login...
Here's the traceback from ddb:
Debugger(0xc01d545b) at Debugger+0x37
panic(0xc01e5339, 0xc6aa6df4, 0xc0152af8, 0x1, 0) at panic+0x74
zerror(0x1, 0, 0xc6aa6f80, 0xffffffff, 0xc0f3b300) at zerror+0x3f
namei(0xc6aa6eec, 0, 0xc6aa6f80, 0xffffffff, 0xc6aa6e30) at namei+0xac
vn_open(0xc6aa6eec, 0x3, 0, 0xc6558680, 0xc01f572c) at vn_open+0x1eb
open(0xc6558680, 0xc6aa6f80, 0xffffffff, 0, 0xffffffff) at open+0xbb
syscall(0x2f, 0x2f, 0x2f, 0xffffffff, 0) at syscall+0x182
Xint0x80_syscall() at Xint0x80_syscall+0x26
Does this lot mean anything to anybody?
Unfortunately, I can't seem to get a crash dump out of the thing. I've
tried doing both "panic" and "continue" from within ddb, and it looks as
though the dump is being written to disk, but when it comes back up,
nothing.
Here's the config file for the kernel that's crashing on me:

And here's the dmesg for the successful kernel that I'm running which is
pretty much the same but with a couple more filesystems compiled into it
instead of modules. Please let me know if there's any more information
I can provide to help with tracking this down...
