Hi, booting the current aurora CD1 (/aurora/corona/sparc/iso/AL-2.99-sparc-disc1.iso) with the 2.6.23.1-26.5.al3 kernel prints out some call traces during boot: IRQ handler type mismatch for IRQ 2 current handler: PSYCHO_UE Call Trace: [0000000000489914] request_irq+0xd8/0x104 [000000000043d700] psycho_scan_bus+0x8c/0x140 [00000000007aa948] pcibios_init+0x38/0x64 [00000000007a2268] kernel_init+0xd4/0x274 [0000000000427838] kernel_thread+0x38/0x48 [000000000067cfc8] rest_init+0x18/0x5c IRQ handler type mismatch for IRQ 3 current handler: PSYCHO_CE Call Trace: [0000000000489914] request_irq+0xd8/0x104 [000000000043d720] psycho_scan_bus+0xac/0x140 [00000000007aa948] pcibios_init+0x38/0x64 [00000000007a2268] kernel_init+0xd4/0x274 [0000000000427838] kernel_thread+0x38/0x48 [000000000067cfc8] rest_init+0x18/0x5c sh-3.1# cat /proc/interrupts CPU0 0: 47352 <NULL> timer 1: 0 sun4u PSYCHO_PCIERR 2: 0 sun4u PSYCHO_UE 3: 0 sun4u PSYCHO_CE This trace was not present during 2.6.21. The boot proceeds fine though, but since call traces are always reminiscient of WARN_ON, BUG_ON and dump_stack, I though I'd ask. sh-3.1# lspci 0000:00:00.0 Host bridge: Sun Microsystems Computer Corp.
