BSOD in aswSP.sys

[tamras]

I have a Windows XP SP3 system with avast free installed.  Today, it updated the program to 6.0.1203.  This evening it blue-screened in aswSP.sys.  I have a minidump which shows the following:

type: aswsp!LockItem+0x1f crash

unfortunately, this bsod will not get fixed - see this thread: http://forum.avast.com/index.php?topic=81278.msg664526#msg664526 (BarbaBookie msg + vlk reply)

I'm also having BSOD caused by aswsp.sys on both computers running Windows XP SP3.
New Avast free version 6.0.1289 did not solve the problem
Will it be fixed any time soon? 
Many thanks.

@bibik,

Your BSOD might be different from the one presented above in the OP. Please open a separate topic and report all your details: OS, SP, x32 / x64, memory dump, additional info...

If you have a mini memory dump, you could also use BlueScreenView to get more info and post it in your new topic (not here, unless you already KNOW that it is EXACTLY the same BSOD, in which case you already have your answer).
