BAD_POOL_CALLER Stop 0x000000C2

[Ray Parrish]

Hello,

I booted into Windows XP, SP3 on my EMachine T3410 this morning for the
first time in about a week and a half [I dual boot Ubuntu and have been
using that for the most part] and got the error in the subject line
before everything had completely loaded in Windows.

I rebooted to see if the error persisted and noted that on the second
boot that almost everything had loaded, but the chat program [Windows
Live Messenger] was still trying to sign in when the BSOD happened again.

The last time I was in Windows successfully I only used my checking
account program, then shut down, When shutting down I noted that Windows
had downloaded updates as it warned me it was going to install them upon
shutdown.

I've researched it briefly using google, and it seems to be a widespread
occurrence with varying causes. It was recommended that one run
Microsoft's verifier [driver verifier] and also to run a memory test.

I'm pretty sure it's not the memory as I'm running just fine in Ubuntu,
so it must be the update that was just installed.

Does anyone have any other tips on what I might try to do to solve the
problem?

Hello again,

This is an update with what I've tried so far. I booted to Safe Mode and
ran verifier. My computer then rebooted and I attempted to start in
normal mode to run the verification, and almost immediately the computer
stopped on a blue screen with the following error -

IOSystem verification error in ifsmount.sys (WDM driver error 20e)
ifsmount.sys+9123 at F7630123

I'm off to google this, in the meantime any tips or tricks from the
group would be most appreciated.

Thanks for the answer nass. Yes, I did have the ifsmount driver on my
Win XP system and as I previously posted verifier pointed out an error
it was tossing which I looked up at the link you provided. Here is the
info I found there -

0x20C Fatal error The caller of IoFreeIrp is freeing an IRP that is
still queued against a thread. (IRP specified.)

This is the supposed error ifsmount.sys was causing [even 'though it has
been working fine for weeks with no problems before]

Anyway, I un-installed ifsmount and now Windows is working again. ???
What the heck happened to cause this wonderful driver to stop working?

My theory is an update from Mickeysoft broke it some how, but upon
looking in Add/Remove in Control Panel with "Show Updates" checkmarked
the newest update I could find was last month. It's been working fine in
the interim.

I lament that I can no longer access my Ubuntu partition from within
windows, but oh well, I hardly use Windows anymore, and can access all
of the Windows partitions just fine from Ubuntu.
