Symptoms: (This is both on 5.2.1-CURRENT as well as booting off the 5.2.1-RELEASE cdrom) During normal boot, kernel freezes before it even starts init. Ctrl-Alt-Delete does not work, power button must be used to reboot. boot -v reveals 'Interrupt storm on "dc0"; throttling interrupt source'. Thinking it might be a bad network card (though it works fine in XP and worked fine when I had 5.1-RELEASE installed), I removed the card, and I got the same error, just on a different device (pcm0). Booting into safe mode works without incident Booting with ACPI disabled works, however it is *significantly* slower than booting into safe mode (>5 minutes from boot->init started vs. ~1min in safe mode) X 4.3.0 locks up system (cannot ctrl-alt-delete, ctrl-alt-backspace, or ctrl-alt-esc) when invoked with anything but a depth of 8 (might be unrelated, but thought it worth mentioning) Building a new kernel with ddb installed and with debugging symbols, same symptoms appear. Ctrl-Alt-Esc does not work when the system freezes, though if i boot into safe mode, it works just fine and drops me to the debugger. I at one point had 5.1-RELEASE installed on the same system (absolutely no hardware changes), without any issues. Hardware: AMD Athlon XP 2400 (NOT overclocked or tweaked in any way), 512MB ram Gigabyte 7-N400-L1 (nForce 2 chipset) ATI Radeon 7500 gfx card Seagate ST3120026A 120MB ATA/100 HD (on primary ide channel) Plextor PX-W1210A CDRW (on secondary ide channel) Lite-On 10/100 PCI Ethernet Any pointers or additional suggestions to try to narrow down the cause of the lockups would be appreciated
