[Bluez-devel] kill hciattach causes a system error

[divisor]

Hello,

I have the following problem:

when I do 'killall hciattach' then remove card from the slot everything is fine.
when I remove card and then cardmgr kills hciattach it causes a system
error and bluetooth card is no longer available when inserted again
until reboot.

I use card called Belkin Bluetooth PDA CompactFlash Type I Model
No.F8T020 ver. 2 thru  PCMCIA adapter called Bluetooth PC Adapter Card
F8T007

command used for attaching card to hci daemon:

/usr/sbin/hciattach ttyS3 comon

I tried different card types with the same result.

what can you suggest?

kernel: 2.6.10, Gentoo Linux 2004.3

bluez version: 2.12 (tried 2.14 with the same result)

kernel error:
