After booting sometimes I get the same message and linux hangs. Problem 2: syslog message "irq 18: nobody cared!" followed by a call trace repeats while booting and while running linux. On the bottom of this mail you'll find an extract of /var/log/syslog showing this error. My system is a P4 630 with em64t, ASUS P5GD2 Premium board (ICH6 chipset) and nvidia 6600GT PCIe graphic card. I'm running a self compiled kernel 2.6.12rc4 but I've had these bugs in self compiled kernel 2.6.11.8 and default debian kernel 2.6.11-9-em64t-p4-smp too. The default debian kernel 2.6.8-11-em64t-p4-smp seems to be the only one where problem 1 does not occur but problem 2 does. /var/log/syslog: ...
