------- Comment #12 from [EMAIL PROTECTED] 2007-08-06 00:53 ------- Created an attachment (id=12268) --> (http://bugzilla.kernel.org/attachment.cgi?id=12268&action=view) disable ioapic when parsing nosmp That maxcpus is zero means that the system will disable ioapic and only use one processor. When nosmp is declared in the command-line the system will skip setup_io_apic and the secondary 8259 interrupt controller can't be configured correctly. Unfortunately some external interrupt sources are connected with the secondary 8259 controller. So the system will report the loss of interrupt, for example IDE controller. The proposed solution is that the system should disable ioapic by setting skip_ioapic_setup to one when parsing nosmp. And it is noted that the flag of skip_ioapic_setup should be set before parsing the configuration of Local and IO apic. Because maxcpus=0 is the synonym for nosmp,the ioapic should also be disabled according to the valule of maxcpus when parsing maxcpus -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
