The xenU kernel in current -unstable tree seems to crash after bootup, having used just 0.1 seconds of CPU time: # xm create kernel=/tmp/vmlinuz Using config file "/etc/xen/xmdefconfig". Started domain TestDomain, console on port 9640 # xm list Name Id Mem(MB) CPU State Time(s) Console Domain-0 0 170 0 r---- 817.2 TestDomain 40 32 0 ----c 0.1 9640 This is with the xenU_defconfig from the xen bk tree, though the same crash has also been observed with the Fedora rawhide kernel. One place where the system crashes is at dmi scan time, because __ioremap() is a "return NULL" when CONFIG_XEN_PHYSDEV_ACCESS is not defined, which makes dmi_iterate's memcpy follow a NULL pointer. The next xenU crash seems to be in parse_args - no idea what's causing that, or why xen0 seems to be working fine ... --- arch/xen/i386/kernel/dmi_scan.c.orig 2005-01-12 14:55:14.000000000 -0500 +++ arch/xen/i386/kernel/dmi_scan.c 2005-01-12 16:06:27.000000000 -0500 @@ -105,6 +105,8 @@ char __iomem *p, *q; for (p = q = ioremap(0xF0000, 0x10000); q < p + 0x10000; q += 16) { + if (p == NULL) + return -1; memcpy_fromio(buf, q, 15); if(memcmp(buf, "_DMI_", 5)==0 && dmi_checksum(buf)) { ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
