(Yes, the system is "old-ish", but is very stable) * pciconf -lvcb output does not list pcib0, so I cannot get further details= of that device. * I don't know when this problem began. It may have been there for some ti= me.=20 Machine previously ran stable/9 (I moved to stable/11 3-4 months ago; full = OS reinstall). * I believe _OSC comes from ACPI DSDT table, and that this particular attri= bute is *very* important depending on what device (UUID) it's referring to -- bu= t I cannot figure out that UUID. This message is therefore of concern, especia= lly because it doesn't disclose what buffer/integer may have overflowed. I am = not worried about security, I am worried that there is a particular PCI-level feature or aspect that is incorrectly being handled. I will attach several things: * acpidump -dtv 2>&1 output * acpidump -dt output * pciconf -lvcb output (don't think this will help, see above) * dmesg output I am hoping someone has some idea what rXXXXXX commit may have introduced t= his. I can roll the system back to a previous commit for testing, but I cannot simply roll back one commit at a time -- this would take literally weeks. = I do believe there were some recent ACPI changes, however. --=20 You are receiving this mail because: You are the assignee for the bug.=
