Hi folks, I just upgraded my box to 2.2.5 a few days ago. It was running quite happily as a 2.2.2-STABLE box, but now it panics pretty easily. It even paniced during the install several times. To get the OS installed I removed all but 16M of the RAM thinking it might be a problem related to the mysterious 48M install preoblem I hard about on previous releases. This did work. I have since reinstalled the RAM and, well the panics are back. I am doubtful that my memory went bad during an install. It would be an odd coincidence, so I am suspecting some other bug is at play here. One time during an install panic, I got the following message: vm_page_free: pindex(-260407040), busy(0), PG_BUSY(0), hold(6) I cannot say what the full panic message is because I was on a vty1, not vty0. The machine always reboots before I can see the panic message, so I recompiled it with the DDB_UNATENDED option. (I believe this is the correct option to get the system not to reboot automatically after a panic.) Well, the new kernel will not boot fully. It hangs when trying to access my second SCSI controller, a BT 747S. The system doesn't panic, but I cannot go multi-user without the second SCSI card, so I need to reboot the original kernel. Oddly enough the BT driver prints out messagesa about the BT742A not responding. Does anyone have any suggestions? The BT747S is a recent addition to my system, but noe of the error messages point to it being a problem until I add the SSB option to the kernel. This ideally should not affect the success/failure rates for booting. FYI, so far the only thing I have tried in terms of kernel customization was to remove the bounce buffers options. This didn't help with the panics. I will try a fully customized kernel shortly. I still have unconfigured devices installed. thanks, Adrian -- adrian@virginia.edu ---->>>>| If I were stranded on a desert island, and System Administrator --->>>| I could only have one OS for my computer, Neurosurgical Visualzation Lab -->>| it would be FreeBSD.
