Bug #: 53122 Summary: X lockups / Classification: Unclassified Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: 201208bugzillaz@moo.uklinux.net

Upon swapping video cards, I have started getting intermittent freezes of X on my Slackware65 13.37 AMD Opteron box (kernel 3.4.4)

The display freezes up totally, including mouse pointer; occasionally there are short (eg ~10s) freezes which might be related, and usually it happens when web browsing (mostly when there is embedded flash on the bbc.co.uk olympics pages)

I hope the below is sufficient info; I need to swap video cards back because I can't afford such lockups ATM.

Here's the lspci lines: 0a:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4550] (prog-if 00 [VGA controller]) Subsystem: Giga-byte Technology Device 21ae Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 74 Region 0: Memory at d0000000 (64-bit, prefetchable) [size=256M] Region 2: Memory at f0500000 (64-bit, non-prefetchable) [size=64K] Region 4: I/O ports at 4000 [size=256] [virtual] Expansion ROM at f0520000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: radeon Kernel modules: radeon

This appears in /var/log/messages (if I wait 20+mins, it seems to unfreeze fairly reliably)

There is no error logged by X, but here its (but note that I run 6 simultaneaous X's on vt7-vt12). I've attached a log file
