BUG: failure at drivers/bluetooth/bluecard_cs.c:552/bluecard_interrupt()!

Kernel panic - not syncing: BUG!

Follow-ups

--- Sonic Zhang 2009-07-21 03:30:24

This bug is root caused to be the same bug in CPLD logic of the CF/IDE/NAND

add-on card. The interrupt out PIN of CPLD is set high by default rather than

correct tristat.

--- Michael Hennerich 2009-07-21 06:08:54

This bug is caused by the CONFIG_DEBUG_SHIRQ option being enabled.

The bluecard_cs card service driver is not prepared for spurious

interrupts caused by CONFIG_DEBUG_SHIRQ.

So the bluecard_cs card service driver needs to be fixed.

Return IRQ_NONE instead of BUG_ON().

It can boot without crash now.

Close this bug.
