On 5.4-PRERELEASE Sat Mar 12 10:56:24, I get the following: umass0: Hewlett Packard HP USB CD-Writer Plus, rev 1.00/0.01, addr 2 umass0: CBI reset failed, TIMEOUT umass0: CBI reset failed, TIMEOUT umass0: CBI reset failed, TIMEOUT umass0: CBI reset failed, TIMEOUT umass0: CBI reset failed, TIMEOUT umass0: at uhub2 port 1 (addr 2) disconnected umass0: detached (Note that each timeout message is two minutes apart, so the above process takes 12 minutes). On 6.0-CURRENT I suspect I'd have got the same if I'd have left the drive in long enough, but instead, being impatient, I removed it after about 60 seconds and recieved a panic in camisr(). umass0: vendor 0x03f0 HP USB CD-Writer Plus, rev 1.00/0.01, addr 2 umass0: at uhub0 port 2 (addr 2) disconnected Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xdeadc116 fault code = supervisor write, page not present instruction pointer = 0x8:0xc04500ab stack pointer = 0x10:0xcb758cdc frame pointer = 0x10:0xcb758cf4 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 curent process = 34 (swi2: cambio) I'm happy to test anything you want me to try, but as this isn't my CD writer, it may take a while... Thanks Gavin
