next in thread | raw e-mail | index | archive | help
I get very consistant panics when doing ``find . -type f |xargs grep
foo'' on a Solaris CDROM in my Plextor 8x CDROM drive (device cd0). I'm
not sure how to proceed in fixing this.
The core files from the panic seem to be useless -- I can't get anything
useful out of ``where'' with a kernel w/debugging symbols:
savecore: reboot after panic: vm_fault: fault on nofault entry, addr: c2923000
savecore: writing core to /var/crash/vmcore.2
savecore: writing kernel to /var/crash/kernel.2
(kgdb) symbol-file ./kernel
(kgdb) exec-file /var/crash/kernel.2
(kgdb) core-file /var/crash/vmcore.2

panic messages:
---
dmesg: kvm_read: invalid address (c026ed38)
---
#0 0x2520656c in ?? ()
(kgdb)
In DDB I get:
panic: vm_fault on nofault entry, addr: c2b08000
