Hello,
I have, more or less, the same problem as michaelk: when I hibernate my computer, then restart it, I have a BSOD, with the error "BAD_POOL_CALLER", error 0x000000C2, parameters 0x0000007 and so on.
I have Vista SP1, Avast antivirus, and Comodo latest version (3.0.22.349).
But the problem was the same without SP1 and with previous versions of Comodo.
My minidump seems indicating that the problem come from a driver: inspect.sys
I wonder if it would be possible for the developpers of Comodo to release a special debug version of that driver, in order to obtain more information, by producing a detailed log file for example.
Because it seems to be very difficult to analyse the problem at booting.
I would'nt like to choose another firewall, as Comodo is powerful. But It is painful to have this problem everyday.
I should mention that I have no error on normal booting, juste with hibernate and suspend modes.
I would thank any help.

Has there been any news regarding a fix for this bug? I'd really like to go back to CIS but I had to stop using it because of this.
