Hi all,
After updating the sources to 9.0-STABLE and building a custom kernel I
get a interrupt storm on irq10, from messages I get that different devices use
irq10.
It starts after loading ums0 and wlan0 and ath0 times out then.
Rebuilding the GENERIC kernel en booting does not give this interrupt
storm.
In the messages from GENERIC I see that the devices sing irq10 with the custom
kernel
use different irq,s
What device or option did I comment out in the custom kernel that
triggers this?
In /etc/make.conf I have
MODULES_OVERRIDE= cd9660 cd9660_iconv msdosfs msdosfs_iconv linux linprocfs
so only the modules I (might) use are being build.
The uname -a without this problem
$ uname -a

This is with the GENERIC kernel, nothing is using irq10.
Below you find output of pciconf, the custom kernel config and output of
messages. Thanks in advance
