Package: linux-image-2.6.18-3-sparc64 Version: 2.6.18-8 Severity: critical Tags: patch Justification: breaks unrelated software
Hi, at first: if the severity may seem inflated feel free to adjust it. Well start with the easy things: my hardware is an old Sun Ultra 5. I added an USB 2.0 controller because I do not have a type 6 mouse, only a keyboard (output of lspci concerning the controller): 02:03.0 USB Controller: NEC Corporation USB (rev 41) 02:03.1 USB Controller: NEC Corporation USB (rev 41) 02:03.2 USB Controller: NEC Corporation USB 2.0 (rev 02) The mouse works but at boot I get this: Kernel unaligned access at TPC[1000c9e4] ehci_hub_control+0x54c/0x68c [ehci_hcd] Kernel unaligned access at TPC[1000c9e4] ehci_hub_control+0x54c/0x68c [ehci_hcd] Kernel unaligned access at TPC[1000c9e4] ehci_hub_control+0x54c/0x68c [ehci_hcd] Kernel unaligned access at TPC[1000c9e4] ehci_hub_control+0x54c/0x68c [ehci_hcd] Kernel unaligned access at TPC[1000c9e4] ehci_hub_control+0x54c/0x68c [ehci_hcd] According to http://lkml.org/lkml/2006/9/22/326 >> A 2.6.18-rc kernel compiled with gcc-4.1.1 will throw a few >> unaligned accesses when I initialise USB by inserting a USB memory stick. >> Removing the memory stick then results in PCI errors and other breakage. Well, I do not have any USB mass media which is dispensible and as this may (or may not) kill data I opted not to try.
