I'm having some problems with -CURRENT locking up, I'm hoping maybe
someone will have some suggestions.
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
