Last Friday was the <a href=\"http:\/\/www.gigliwood.com\/weblog\/MacOSX\/2nd_Report-an-Apple.html\">second Report-an-Apple-bug Friday<\/a>, so it seemed fitting that I had filed this bug over the weekend.<\/p>\n<p>My bug relates to a small problem I found &#8212; a 100% reproducible kernel panic. The panic code is actually the same code Graham and I developed for the <a href=\"http:\/\/www.kernelthread.com\/mac\/challenge\/result\/\">Mac OS X Experts Challenge<\/a>. While Apple fixed the panic caused by panpipes, it turns out that our code triggered another related bug, but not the same bug, which also results in a kernel panic.<\/p>\n<p>Here&#8217;s the backtrace (from 10.4.2) for anyone who feels like working out where the bug is by themself:<\/p>\n<pre>#0  0x0026d9e4 in threadsignal ()\r\n#1  0x002a529c in catch_exception_raise ()\r\n#2  0x00043340 in exc_server_routine ()\r\n#3  0x0004326c in exc_server ()\r\n#4  0x002a5110 in macx_swapinfo ()<\/pre>\n<p>It&#8217;s fairly simple (<code>threadsignal<\/code> isn&#8217;t all that long), and follows on from the theme of the panic Amit used in the Mac OS X Expert&#8217;s Challenge. It should be fairly easy to work out what the trouble here is with reference to panpipes.<\/p>\n<p>For the record, the Radar ID is 4225451.<\/p>\n<p>I&#8217;ve got an idea for my bug for this Friday, so let&#8217;s see if we can carry on without Dan for a week, we&#8217;d all hate to let him down.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>My bug relates to a small problem I found &#8212; a 100% reproducible kernel panic.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2,4],"tags":[],"_links":{"self":[{"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/posts\/8"}],"collection":[{"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/comments?post=8"}],"version-history":[{"count":0,"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/posts\/8\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/media?parent=8"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/categories?post=8"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.allocinit.net\/blog\/wp-json\/wp\/v2\/tags?post=8"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
