Subject: Hostap_cs shared irq oops
Date: Sun, 10 Dec 2006 05:42:08 +0100 [thread overview]
Message-ID: <457B9020.1040101@latinsud.com> (raw)
Hi, I recently upgraded to kernel 2.6.18.2 and noticed these problems:
- I realized that having CONFIG_ISA=y makes it always crash when i
insert the card (complains about unexpected LVT TMR interrupt). So i
disabled Isa.
- Hostap_cs gets a shared Irq (this didn't happen with kernel
2.6.15.6). It crashes if the interrupt is triggered while the device is
not fully initialized (Error is: "Divide error 0000 [#1]"). I can
workaround that by using a flag and inserting a "if (!my_init_flag) {
return IRQ_HANDLED }" at the begining of the irq handler.
- I don't know much about irq allocation. Can i try something to get my
separate irq back?
- Should i try different configuration or 2.6.19?
- Should hostap_cs be enhanced to support shared irq?
I use debian etch. Laptop is a G200N 1.7GHz Centrino.

Thanks, please CC me if you can (works both with or without the "_nospam").
