My system panic's from the KASSERT() call at line 2269 after dsdt.c was updated to 1.210.
All I have is the basic panic message and the dmesg from the last known working snapshot kernel. I tried to get more information but my USB keyboard does not work in the kernel debugger, and my on-board keyboard no longer works at all (I use the laptop as a desktop now). I typed up everything I could see of that panic message by hand. Any patches that need to be tested I will be glad to try out. Here's the panic message and dmesg output. --- panic --- acpi0 at bios0: rev 2panic: kernel diagnostic assertion "rgn->v_opregion.iobase % sz == 0" failed: file "../../../../dev/acpi/dsdt.c", line 2269 Stopped at Debugger+0x9: leave panic() at panic+0xfe __assert() at __assert+0x25 aml_rwgas() at aml_rwgas+0x1fd aml_rwfield() at aml_rwfield+0x205 aml_eval() at aml_eval+0x1ae aml_parse() at aml_parse+0x183d aml_parse() at aml_parse+0x1ff aml_parse() at aml_parse+0x1ff aml_parse() at aml_parse+0x1ff end trace frame: 0xffffffff81ef48f0, count: 0 RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!
