Subject: Re: ax25 rose Re: kernel panic linux-2.6.27-rc7
Hi Jarek,
Yes this is a vanilla kernel, which makes it interesting to debug.
I forgot to Cc: Ralf and put it now on copy of this message.
Thank you for the patch I applied.
Collected data includes both events I already reported, first the
inconsistent lock state, second the kernel bug followed by a kernel
panic. The second event only occured after I intentionally started,
after a while, FPAC application using rose protocole .
